I really enjoy your new format, explaining how the different system on a super yacht work is much better then walking the docks and telling us which yacht is in port , very well done
Well done explanation, during the ‘90’s we had a HUGE antenna almost 5’ diameter. I had to program the system daily as I shut it down at night. Crazy old stuff!
Its kind of like back in the day when GPS was not a full out option for the recreational boaters...I remember having a GPS/Loran-C combo unit due to the inaccuracy of the GPS system. Thats what the Star~Link kind of reminds me of at this point. *Flying Fox...What a beauty!!! *Thumbs up as always for repping the Porsche gear!!!
ben dover one difference though, GPS was fully capable of being as accurate as it is today back then. The GPS signal was intentionally broadcast to be slightly inaccurate for all non US military uses.
Awesome video! Me and my family sail around the world on our own small sailing yacht. We pay USD 150 p/m for 2kbps! Just enough for basic email and weather forecast. Sometimes friends ask why we don't update social media from at sea. I'll point them at this video in the future😀.
Fantastically explained and well researched. I enjoyed the full oversight. Thanks. On a different topic. Im curious as to the noise while holidaying on a super yacht compared to living at home. Its not covered anywhere I can find. I'm not talking Dilbar, more typical 50m +/- yachts. I know there is lots of sound insulation but there must be noise/vibration form engines/generators/pumps/galley/other systems (particularly early in the morning)/crew working/guests walking around above/below you/doors/showers running/toilets flushing/water rushing through pipes etc. But also restrictions guests have to be aware of - I'm sure you cant have a really long shower and such, that we take for granted on land? Maybe, its a subject you would consider covering...?
Noise is quite different from yacht to yacht depending on age but I'd say most modern yachts 30 meters+ have great sound insulation and mostly you will hear if someone is running or jumping around on the deck above you. It is pretty much like a really nice house that allows you to travel and has a crew of people at your service. The engine room is incredibly insulated and the engine noise will mostly be heard from the back of the boat while running. They're incredibly luxurious and have the most extreme standards for perfection and comfort for the guests and owners. And yeah, you can shower for as long as you'd like. Hot or cold water from the tap is almost instant too.
I can add some perspective. I went out on a yacht for a few days years ago. When under way, there was a very low rumble you could feel more than hear. Kinda soothing, really. When at anchor and there is wind, there are sea sounds. gentle slapping, sloshing noises outside, but nothing you could hear inside. We had no heavy seas or hard wind, but I imagine thats pretty noisy. Also the yacht matters. this was a ~50ft Bayliner- el cheapo by yacht standards. I bet a Nordhavn or Princess is very quiet.
i know Im asking randomly but does someone know a method to get back into an Instagram account?? I stupidly lost my account password. I would love any tips you can give me!
Really interesting video - knew most of it already (even the VSAT - I was VSAT specialist on mission in ex-Yugoslavia in the mid 1990s), but nice to see it explained so simple and clearly, with proper video examples of what you're talking about - keep up the good work.
I’m in the satellite and austere location communications industry and I just have to say that you did a GREAT job in this video! Well done... throw things. 1) look into Medium Earth Orbit options. Such as O3b. 2) you mentioned a few different really junky routers for 4G and wi-if. There are MUCH better solutions out there for these applications that offer acceleration capabilities, caching capability, seamless fail over and back between technologies and some even offer very secure vpn technologies, VoIP PBXs, and other very interesting non standard technologies that may be interesting to yacht owners. There is an excellent company located in the Ft Lauderdale FL area in the US where the owner is an expert in all things maritime communications.. He did this type of work while in the US Coast Guard even! Look up Galaxy One Satellite Communications. I have no professional tie to this company, but I have used them in the past and they are amazing to work with.
Only in Europe can you say that speeds are increases every year while prices are decreasing. In the US internet speeds only go up in large cities in any meaningful way, and it's NEVER cheaper. The prices are always increasing even when the speeds aren't increasing.
Agreed. US companies enjoy monopoly in many municipalities (grease the right palms on city council - get a monopoly). The lack of competition coupled with long term municipal contracts allows companies to take full advantage of the consumer. That is not to say they aren't upping the speeds but, as you said, that speed comes at higher cost.
Cell phone contracts in the US are incredibly expensive even compared to an irrelevant back water like the UK, and coverage outside the cities is not good.
Good to see you got back to the U.K. !! As ALWAYS great video and excellent content. Thanks for the explanation regarding starlink,,, I hadn't taken the time to read/watch more about it. Stay safe, take care. 👍👍
Great topic! Internet is a cost that a lot of people who are out of the loop wouldn't even consider when thinking/talking about yachts. $900, 000.00USD annually is a whole lotta dough, no matter who ya are...WOW!!
Thank you Thank you Thank you ... You have a wonderful simple & understandable way of explaining the most complex of topics and your numbers should be far greater .... now if only I can get my TV remote to do what I need it to do ! :)
Thank you sir. Your explanations are always excellent.I enjoy your work all most as much as you may .Looking forward too your next video .God Bless . Amen !
Nice video. There is already over 500 Starlink satellites on orbit, and they are building them at speed of 6 a day. Hopefully they get initial test customers up and running before end of this year.
@@thomasberglund6400, they only need ~750 to start initial coverage for Canada and the northern US later this year. They launch 60 satellites at a time and they have been doing launches about twice per month. They will likely have enough satellites in orbit in 2 to 3 months to get started. They only need about 2000 satellites for worldwide coverage which would be about 12 months from now at the current launch rate. The 42,000 number is the max number they are licensed for, not what they actually require to be operational. I'm sure they will ramp things up as things progress, but even at the current pace this technology isn't too far away.
I'm an Aerospace engineer, and you mentioned something I hadn't actually thought about for Starlink. The first orbital shell currently being filled with satellites at 550 km should provide complete worldwide coverage from bottom of Norway to New Zealand (+/- 56 degrees North), but they do require ground stations as you said. However to link together all the continents there will need be some ground stations in the ocean, either on islands or floating platform/ships otherwise London can't talk to New York. Nobody cares about covering literally the entire ocean with ground stations though. The 550 km orbit satellites has coverage area about 940 km wide, which would cover most of Iceland from a ground station based in England (ignoring Iceland being too high latitude). They would also make sure all of the popular transatlantic/pacific airplane routes have full coverage since that's one of their target markets. But yeah, most of the ocean would still end up left uncovered for at least another 5-10 years.
I've heard the idea of using ship's crossing with technology onboard as relays. I don't know how that will work though as of course it requires vessels to be constantly in those areas with the right equipment. Currently the Geo satellites only give small amounts of bandwidth on Atlantic crossings so any improvement on that would be welcomed by Starlink.
The sats have interconnectivity via laser. It's not going to be activated for awhile yet, but not a decade from what the engineer at SpaceX say just 2 or 3. But it negates ground stations across oceans completely as said in the vid.
My favorite service call was to climb up and take the cover off to unwind a dish. While at anchor, yachts would slowly rotate with tides and currents while the dish maintained tracking. When the dish reached the limit (+/- 3 rotations?), it would shut down. I'm guessing modern trackers would have remote and automatic reset functions which don't require removing the lid 😅
For lower orbit satellites like Starlink and OneWeb (with the UK leading a rescue) can use electronic aerials. They're just a flat horizontal panel that doesn't move. They are electronically 'aimed' at where the satellite is.
@@jannikheidemann3805 No, everything is shielded copper basically. It's all LBand BDE and ADE and the rotary joint carries DC to power the LNB. The power ring carries the 220VAC.
Oh boy did the predictions about Starlink were off. 10 years he said, and in less than 4 years Starlink already revolutionized the maritime internet, not only because vessels using it but also pressuring the prices down. Never underestimate a bunch of math and engineering geniuses backed by a "total commitment or dead " billionaire. He has a new video, excellent as always, and clearly nobody can blame him, many were saying it would not work, ever, including people that are "experts at talking about space stuff"
A solution, or base idea of a solution, if all vessels (Trans Atlantic certified at least, including yachts, cruise ships, cargo vessels) could all have an antenna to relay the information. Instead of a satellite being in space, the 'satellite' would be an antenna on every vessel. This would work in the same way repeaters work with Amateur Radio. The signal would keep getting repeated from vessel to vessel til it reached the land based station where it would connect to landline internet. APRS in amateur radio works this way as well. It sends the signal from repeater to repeater to repeater. Radio signals travel at the speed of light. Talking on HF frequency from Chicago to Europe is instant. I think they could explore this idea for maritime vessels. It'd be a heckuva lot cheaper than $900,000/yr! Excellent video!!
Nice to see you back and in good health . When I get my super yacht there will be no internet , you think am paying them prices for the crew to play angry birds 😂
Iridium satellites have being doing inter-satellite links via Ka band for years. Starlink will have it's Ka band or Laser inter-satellite links working fairly shortly...
There are both megabytes and megabits, eight bits make a byte. But comm speeds are measured in bits, because the comm protocols carry overhead of various levels, so there’s no direct one-to-one correspondence between a raw data connection’s speed in bits per second, and the resulting user-facing payload transmission (usually measured) in bytes. So you transfer files having a certain number of bytes over a comm link with a speeds measured in bits per second, but you can’t just use a factor of eight to calculate transmission times, due to protocol overhead (handshakes, routing, checksums, etc.) which eats up valuable bits… In short: if you’re talking about file sizes it’s usually megaBYTES, if it’s transmission speeds it’s usually megaBITS/s, but theoretically one can use them interchangeably, provided one uses the proper conversion factor. Now, to make it more complicated: in infinite wisdom (sarcasm) kilo, mega, etc. used to be base-2 derived, so a kilobyte weren’t 1000 bytes, but 1024 (2^10) bytes. Mega was 2^20 thus 1048576 not 1000000, etc. Marketing people realized, that lowered the numbers, and switched to base 10, thus kilobytes are now 1000 bytes, no longer 1024, etc. Starting around the year 2000, a standard was passed much to the liking of the marketing folks, and thus… The old base-2 units are still in use, sometimes by their old names, sometimes by their new fangled names. So the old Mbit is now the MiBit (pronounced mebibit) (2^20 bits), while the new Mbit (megabit) is now officially simply 1000000 bits. So, there could also be data rates reported as “mebibit per second”, and if you don’t know about this mess, you might just think someone has a speech impediment… Confusing enough? 🤷🏻♂️
Thought I already knew a lot about this topic, but guess not. Thanks for all of the fascinating info! Love these technical videos. Perhaps a topic for a future video is the difference between the tech for most regions vs. communications tech for polar regions? Actually, would be cool to just hear about general tech (machinery, navigation, hull construction, etc.) required for polar exploration. Thanks again!
VSAT = Very Small Aperture Terminal. That was an easy one (okay, yeah, I'm a telecom geek). Thanks for doing this video, very well done. I'd like to see you dissect the antenna array of a megayacht like Flying Fox and explain why some of the antennas are so large. My understanding is the 3+ meter monsters will give you at least some coverage at extreme latitudes both north and south. Are those the dual C & Ku band VSAT or are they TV antennas?
The large antennas 96in. to 144in. are C-band. The 40in. to 60in. are Ku band. The larger the reflector the higher the gain. The higher the frequency the more the atmosphere attenuates the signal. Domes do not contain arrays, just a parabolic reflector that tracks the satellite and feeds the HF signal into the very small aperture that then down converts the HF into L-band. The motion and control for the antenna is MUXED or multiplexed onto the receive cable of the antenna. The transmit just carries the tx and sometimes voltage to power the BUC or transmitter. Musk satellites will utilize phased array antennas which have a much lower gain than a parabolic reflector and rain fade will be even greater than on a Ku.
Cross-links have been in use for decades - the US military on MILSTAR and AEHF; commercially on Iridium (launched in 1999); and more recently by the Europeans. Starlink purportedly to host cross-links much sooner than 2027, and Jeff Bezo's Kuiper satellite network, plus Telesat's LEO network all have baselined cross-links. In fact there are about 10 major constellations being built for broadband, so will have plenty of choices (of course, not all will succeed). Interestingly, the short video segment within this video shows traffic being routed between NY and London, which uses cross-links (notice how the redlines changed direction as the satellites moved in orbit)? Good video - thanks for producing.
Here, the most common for moorage clients, you have to have an account with ShawGo WiFi to have internet access, as well as the wired connection options ( local service provider accounts required ). Shaw Cable clients have a ShawGo Wifi account included, if you just want the wifi account I think it is a fairly cheap $5 or $10 a month in Canadian dollars ( 35-40% less in US dollars ) One sat network that even has polar region coverage is iridium, their satellites are not in geosynchronous orbits, instead they orbit lower and the equipment on board has to switch rapidly between satellites. They have a higher number of satellites so you should have 2 or 3 available at any time although in areas like the Norwegian Fiords (sp?) the high cliffs can block signal. The same land blocking signal can happen here in the PNW / Inside passage. This area also has limited cellular coverage with a large percentage of the cruising area having no cellular signal.
Update - Starlink are already beginning to launch new version satellites with satellite - satellite laser communication between them - the future of global internet coverage is much closer than you think. Of course the priority is to scale to the land based populations and these can be served with ground based relay stations.
Geostationary satellites from Inmarsat are okay, so GMDSS runs over there. What do you think of iridium? They use LEO satellites at an altitude of around 780 km, even over the poles. Starlink is just another provider and with this amount of sheet metal that Starlink shoots up into orbit, it affects other, established providers and wastes valuable resources! Great videos and great contents, I like your work. 👍👍👍
Iridium is pretty outdated compared to Starlink. It uses very large/heavy/expensive satellites that have limited bandwidth. Iridium service is expensive and relatively slow because of this. Starlink is using much smaller/lighter/cheaper satellites (they can launch 60 at a time) with much more powerful hardware. Therefore, Starlink is likely going to be significantly faster, more affordable, and much more scalable compared to Iridium. Honestly, I think Iridium is going to be almost completely obsolete once Starlink is online. Iridium would still have a market near the poles, but that leaves them with a handful of customers paying for the entire infrastructure. I doubt that will be a viable business model in a few years.
One nice tidbit of information. SpaceX actually uses the same kind of gyro stabilized vsat antennas that are used on ships as uplink antennas for there ground stations. And a single superjacht permanently cruising in the middle of the Atlantic acting as a data relay would be enough to bridge the gap in coverage between Newfoundland and Ireland.
By the time I’ve got enough money to buy a yacht, the Starlink will be old news and something even better/cheaper/faster will have come along! Will be interesting to follow the progression of this technology
As always very professionally delivered great information and very informative need to wait until I win the lottery to pay these exorbitant costs Regards H
Greetings from Colorado! Lovely piece. Yours is a primary emotional resource/outlet to which I turn for relief when the enTIRE news universe seems dark to blackout. The Donald. Covid. Black lives. Veterans suiciding to the tune of 22 per DAY! 49 shootings in SCOOLS in 2919 in US... on and on AND ON! Until I get to sea and visit your life which you share with a calm and erudite voice. Thanks, brother
Many of those shootings were not in schools. The press includes ANY gun event within a mile of a school in that number. Some of them were BB guns where one person accidentally shot another with it and it was almost a mile from the school and the injury was VERY minor. The press LOVES to inflate those numbers to make it look like we in the US are a bunch of crazed gun nuts. So this number is not accurate at all. No offense to you.
Also, military personnel do NOT suicide at a rate of 22 per day. Not even close. The current suicide rate per month is 26. So that's less than one per day. ANY number of suicides is terrible, but your number claim is way, way off. The current rate is calculated by a rate per 100,000 military personnel. There are right at 1,300,000 personnel in the US military. And the current suicide rate per year is 24.8 per 100,000, on average. So, you multiply 24.8 times 13 and you get 322. Divide that by 365, and you get less than one per day. Please do a bit of research before posting in regard to hot-button topics. I just don't like talking about such things here, anyway, because like you said, this is a place to escape all of that. But I had to correct those numbers with some facts.
If I were designing a Worldwide Satellite Network. My first group of satellites would be the space to ground satellites. SpaceX has a habit of constantly changing the design of *EVERYTHING.* Which is pretty interesting. I wish I could remember the video I saw when a representative from SpaceX (probably an engineer) was discussing the first 60 (don't quote me on the number) wouldn't be able to communicate with each other. But the follow on satellites would. And that there will be at least 2 altitudes the satellites will be flying in. In addition to all the orbital planes they will be using. Of course this is all subject to change.... This is SpaceX after all. 😂 Great video.
Excellent - all the info you wanted to know including interesting tangents that were brief. Pleasant voice. I feel like I got the truth from an "insider's" point of view.
I just got a RUclips connection to your video lol. Very good vid and I will definitely watch more. Although its already a few months back since you posted this (and might have already answered it in one of your next vids which I'm catching up too), I wonder if the Starlink project satellites will interfere with the VSAT? Will they block/interfere with signals to higher orbit satellites? i.e. will a VSAT system become obsolete in the near future?
Starlink may be a great option for places like the Caribbean/ Mediterranean or other areas with lots of islands. Not great on long oceanic passages but for a lot of areas where people are cruising still probably will be viable resource to throw into the mix.
The update to this would make this not true. Starlink's issue is node saturation... basically, it's gonna be great for areas with low usage and mediocre or worse in densely populated areas... so the BEST uses for Starlink will be rural areas and at sea.
internet vs satellite. i had a minute conversation on the 31st of December with my girlfriend at the time to wish her a happy new year from Antibes to Portugal from a motor yacht. . and it was on a sat phone in 2001 and it cost almost as much as i as got paid for the day. from a motor yacht to a land line. so that was the cutting edge of communication 21 years ago.
Fantastically well explained. There are more technologies, there are also cheaper packages that you could opt for .. but .. and this is the problem: these yachts move about. So it's always the issue of weighing up hassle vs cost. The golden middle way is the solution. And yes .. roaming connectivity at sea is most certainly one of the most pricey issues you can run into.
00:20 In Longmont (northwest of Denver) 1GB (price guaranteed for life) costs US$59.99 It is a public utility so the address assured the rate and I am assured the rate no matter where I live in Longmont
I remember a few summers back that my friends and myself started arguing about internet on your boat. Where we were at was our home Waters of Maryland right next to the naval academy in Annapolis. It started off with who has a better cell phone service on the water and then we change that subject to how is the internet. Of course where we were at everybody had great service. My wife and myself started talking about how when we go on longer trips and we are in the middle of the Atlantic ocean that other than my emergency satellite phone that we do not have internet service most of the trip. Then that is when everyone started telling me that I can get a satellite dish and get internet and TV service anywhere. I explained to them TV service is different and that internet on a boat for one month was over $10,000. Everyone started arguing and telling me I was crazy that there's no way that could be right. So I went ahead and pulled up all the information on my laptop and showed everybody. Then the conversation changed to why would you care you have the money. That was a whole new argument about how you keep your money and not wasting money on ridiculous things. I enjoyed your video and look forward to the next one. .
I was waiting for you to talk about starlink and maritime Internet. It will need a few years to launch all the starlink satelites. What I'm worried about is people who will be watching videos while walking on the streets.
People can already watch videos while walking on the streets. 4G cellular has plenty of bandwidth for video. Starlink requires a transceiver the size of a pizza box so I don't think people are going to be bring Starlink connections on their person.
@@CL-gq3no I was thinking it would lower 4g Internet prices so a lot of people would actually use it to watch videos while walking. Cuz people in some countries can't afford wasting too much data. I hope you get what I'm trying to say. and about the 2nd thing you said, thanks for the info about how starlink works.
As far as I understood, Starlink is stationary only. Check out Jeff Gerling’s video about it. He couldn’t even install his dish (registered to his home) to his sister’s home, for several reasons.
Interesting video . Nice to see our price list in it :) It has been improved since . Regarding starlink beyond the technology the business model is maybe not sustainable. The expectation to get cheaper internet is not going to be matched . By the way they still don’t have the approval to operate on mobility neither an antenna for mobile platforms
the first launch of 60 was unable to communicate with each other and pass the information along but the current launches are fully functional. their current plan only requires 4000 satellites but they have fcc clearance to launch 40k most likely they will never reach this number. although their curent plan does not reach the poles and i do not think it reaches Alaska at all so in those situations vsat is till the only way to go. i am unsure if they have plans to ever cover the poles but i think it is likely as they have a large market if they can get coverage to the uk
Very interesting as always. I had thought that Starlink would be a solution but had not taken the earth stations into account. I wouldn't sell Musk short on this too soon though, if he can land used rockets on a ghost ship in the ocean, he may see the need for a solution here sooner than later.
It will get done, no doubt with that, but communications between satelites are much more difficult than may seem. To understand why you need to know how TCP/IP protocol works (the connection protocol of internet). To put it simple: Every device connected to the network can be considered a "node" and every package of data you send or receive through internet travels between several nodes before reaching its destination. The routing of the package is set in every node individually, there is no default route set for a certain package and every package is treated independently to other packages. Every node that receives the pakage and has to resend it to another node in order to reach the final destination; decides which will be the next node the package will be sent to. That decision is made based on something called "routing tables" and the IP adress of the final destination of the package (which is written as part of the data package). Every new node connected to the network, first thing it does is broadcast its IP adress and receives from the other nodes it is connected to their IP adresses (which will create the routing table on the new connected node). That is "easy" when nodes are constantly connected to the same ones and are stationary, so they don't have to change the routing. For starlink that is much more difficult as, unlike geostationary satellites they have to keep changing land bases constantly and therefore their routing tables, if you add that to the problem of creationg new connections with new satellites aswell it get so difficult, also because even 2 satellites can be "quite close" (astronomically speaking) one to another, they move at about 7 km/s around the earth, and their relative position one to another is changing constantly. Keep in mind that satellite antenas are highly directional to focus power, but that means that they must be pretty much pointing one to another directly to get any signal at all.. Of course you could make omni-directional antenas and receivers which would theorically avoid those problems (directivity and effective area of reception are inversally proportioned and it's a constant that depends only on the wavelenght of the signal, actually is Area/Directivity = [(wavelength)^2]/(4*pi)), but those satellites are not close enough one to another to be able to use omni-directional anthenas without wasting much more energy through signal sent to useless directions than what the satellite is capable of generating through solar panels. All that without getting into other stuff like polarization, clockwise or anti-clockwise... Sorry for the long message, I tried to simplify it without making horrendous mistakes due to the fact of oversimplifying things. But trust me when I say that I could easily write a PDF of over 20 pages just to explain how things actually work for people who already have a notion of everything I would be talking about.
Thanks Javier!! Not sure I completely understand what you were explaining, but I'm very interested in getting a "fix" for the high cost of slow speed Internet at sea. I'll watch for your 20-pg PDF and give it to someone who understands it better!! Cheers.
@@kistosable important point. But there's no reason at all to use IP protocol. The internet backbone uses SONET frames, which encapsulates IP packets. In your house you probably use ethernet packets which encapsulate IP packets. In other words you're free to use what works best. All the routing decisions could be done at the ground station prior to the first uplink. I would be interested to learn how multi-satellite routing actually works. As you say, it's very much more complex than the single-satellite mode being tested now.
@@henryD9363 You are going deeper, I said I wasn't explaining the full thing because as I said, if we have to explain how the whole www works in full detail we can spend here hours writing things most people wouldn't comprehend. You can separate the network into two different ones: the one done on earth and the one done on LEO satellites, but still, the routing protocol should consider the constant changes in position between the two "subnetworks" and the main issue remains. The issue is not establishing a link between earth and a satellite nor the protocols we use for communications. The issue is that LEO satellites move relative to the ground level, and they do fast, so the calibration of the routing must be performed constantly and with high precision as the anthenas used on satellites are highly directive ( as the acronym VSAT suggest). But I'm glad that actually someone could understand my comment. I did my job nice then :). Salutes!
Liked the fly over of the Flying Fox. BTW... in the mid 2000's 45Mbs of dedicated VSAT ran about $150,000 / mo..... so... looks like we are making progress on pricing.. 🤣
VSAT (Very Small Aperture Terminal) is a satellite communications system that serves home and business users. A VSAT end user needs a box that interfaces between the user's computer and an outside antenna with a transceiver. The tranceiver receives or sends a signal to a satellite transponder in the sky.
very well explained especially the starlink part , thanks. are you currently working as a captain ? are you able to say any of the yachts you have captained in the past ? all the best
Good video. Very informative. That's why I like this channel. My suggestion to billionaires: make platforms(like oil rig platform), with cell towers. Start planting them in the well traveled areas. Solar panels, cell tower, floating platforms. Make it happen. If you care.
The land stations are what connect the satellite network to the rest of the internet. If you put them on anything mobile you would be right back where you started with no internet. It's like saying "put your home router in your car so you'll have mobile internet." Clearly that won't work as once you unplug it from the home's wired internet connection.
Actually, Starlink satellites will communicate via laser, thus radically reducing the number of land terminals required. Please refer to Spacex for correct info.
The info in this video is correct. This video was produced in July 2020. Everything said was accurate at the time. And the lasers still don’t work. The satellites still cannot transmit data through each other.
I really enjoy your new format, explaining how the different system on a super yacht work is much better then walking the docks and telling us which yacht is in port , very well done
I will never take my internet at home for granted
Well done explanation, during the ‘90’s we had a HUGE antenna almost 5’ diameter. I had to program the system daily as I shut it down at night.
Crazy old stuff!
As an IT professional who will never own a yacht, I really enjoyed this one!
Its kind of like back in the day when GPS was not a full out option for the recreational boaters...I remember having a GPS/Loran-C combo unit due to the inaccuracy of the GPS system. Thats what the Star~Link kind of reminds me of at this point.
*Flying Fox...What a beauty!!!
*Thumbs up as always for repping the Porsche gear!!!
ben dover one difference though, GPS was fully capable of being as accurate as it is today back then. The GPS signal was intentionally broadcast to be slightly inaccurate for all non US military uses.
JonnyRicter
That’s correct...Thus requiring the combination style units, or one of each back in the day.
Awesome video! Me and my family sail around the world on our own small sailing yacht. We pay USD 150 p/m for 2kbps! Just enough for basic email and weather forecast. Sometimes friends ask why we don't update social media from at sea. I'll point them at this video in the future😀.
Iridium?
Well that's cool
Fantastically explained and well researched. I enjoyed the full oversight. Thanks.
On a different topic. Im curious as to the noise while holidaying on a super yacht compared to living at home. Its not covered anywhere I can find. I'm not talking Dilbar, more typical 50m +/- yachts.
I know there is lots of sound insulation but there must be noise/vibration form engines/generators/pumps/galley/other systems (particularly early in the morning)/crew working/guests walking around above/below you/doors/showers running/toilets flushing/water rushing through pipes etc. But also restrictions guests have to be aware of - I'm sure you cant have a really long shower and such, that we take for granted on land? Maybe, its a subject you would consider covering...?
Noise is quite different from yacht to yacht depending on age but I'd say most modern yachts 30 meters+ have great sound insulation and mostly you will hear if someone is running or jumping around on the deck above you. It is pretty much like a really nice house that allows you to travel and has a crew of people at your service. The engine room is incredibly insulated and the engine noise will mostly be heard from the back of the boat while running. They're incredibly luxurious and have the most extreme standards for perfection and comfort for the guests and owners. And yeah, you can shower for as long as you'd like. Hot or cold water from the tap is almost instant too.
Thats exactly what I am looking for too
I can add some perspective. I went out on a yacht for a few days years ago. When under way, there was a very low rumble you could feel more than hear. Kinda soothing, really. When at anchor and there is wind, there are sea sounds. gentle slapping, sloshing noises outside, but nothing you could hear inside. We had no heavy seas or hard wind, but I imagine thats pretty noisy. Also the yacht matters. this was a ~50ft Bayliner- el cheapo by yacht standards. I bet a Nordhavn or Princess is very quiet.
VSAT = VeryExpensive Satisfaction Always Terrible
Lmfao xD
Aye sir
PCMCIA = People Can't Memorize Computer Industry Acronyms! 😀
i know Im asking randomly but does someone know a method to get back into an Instagram account??
I stupidly lost my account password. I would love any tips you can give me!
@Kane Dillon instablaster :)
i subscribed to your channel because your such a nice bloke, you could literally talk about anything and i wouldve subbed
Thank you 🙏🏻
I’ve subbed , I’ve developed an interest in all things super yacht ! informative and likeable , I am slowly watching all the videos you have made
Great vlog. Glad to see you safe and healthy and look forward to many more !
Really interesting video - knew most of it already (even the VSAT - I was VSAT specialist on mission in ex-Yugoslavia in the mid 1990s), but nice to see it explained so simple and clearly, with proper video examples of what you're talking about - keep up the good work.
Can’t wait for the job advert. Broadband repair technicians required, extensive travel mandatory and must be comfortable working in Zero G 😁👍
I’m in the satellite and austere location communications industry and I just have to say that you did a GREAT job in this video! Well done... throw things. 1) look into Medium Earth Orbit options. Such as O3b. 2) you mentioned a few different really junky routers for 4G and wi-if. There are MUCH better solutions out there for these applications that offer acceleration capabilities, caching capability, seamless fail over and back between technologies and some even offer very secure vpn technologies, VoIP PBXs, and other very interesting non standard technologies that may be interesting to yacht owners. There is an excellent company located in the Ft Lauderdale FL area in the US where the owner is an expert in all things maritime communications.. He did this type of work while in the US Coast Guard even! Look up Galaxy One Satellite Communications. I have no professional tie to this company, but I have used them in the past and they are amazing to work with.
This was/is a Very Good Video. Very well made. Very interesting. Very informative.
I like it a lot. well done!
Only in Europe can you say that speeds are increases every year while prices are decreasing. In the US internet speeds only go up in large cities in any meaningful way, and it's NEVER cheaper. The prices are always increasing even when the speeds aren't increasing.
Agreed. US companies enjoy monopoly in many municipalities (grease the right palms on city council - get a monopoly). The lack of competition coupled with long term municipal contracts allows companies to take full advantage of the consumer. That is not to say they aren't upping the speeds but, as you said, that speed comes at higher cost.
Cell phone contracts in the US are incredibly expensive even compared to an irrelevant back water like the UK, and coverage outside the cities is not good.
Good to see you got back to the U.K. !! As ALWAYS great video and excellent content.
Thanks for the explanation regarding starlink,,, I hadn't taken the time to read/watch more about it. Stay safe, take care.
👍👍
Great topic! Internet is a cost that a lot of people who are out of the loop wouldn't even consider when thinking/talking about yachts. $900, 000.00USD annually is a whole lotta dough, no matter who ya are...WOW!!
Very educational and entertaining. Great content as always.
Thank you Thank you Thank you ... You have a wonderful simple & understandable way of explaining the most complex of topics and your numbers should be far greater .... now if only I can get my TV remote to do what I need it to do ! :)
Thank you sir. Your explanations are always excellent.I enjoy your work all most as much as you may .Looking forward too your next video .God Bless . Amen !
Very informative video 👏🏼👏🏼👏🏼 thank you for sharing 👍🏼
Great vid. As always, most informative.
Haha, mate, that's the flat earth theory up in smoke! 😅
Another great informative video btw.
Nice video. There is already over 500 Starlink satellites on orbit, and they are building them at speed of 6 a day. Hopefully they get initial test customers up and running before end of this year.
@@thomasberglund6400, they only need ~750 to start initial coverage for Canada and the northern US later this year. They launch 60 satellites at a time and they have been doing launches about twice per month. They will likely have enough satellites in orbit in 2 to 3 months to get started. They only need about 2000 satellites for worldwide coverage which would be about 12 months from now at the current launch rate. The 42,000 number is the max number they are licensed for, not what they actually require to be operational. I'm sure they will ramp things up as things progress, but even at the current pace this technology isn't too far away.
I'm an Aerospace engineer, and you mentioned something I hadn't actually thought about for Starlink. The first orbital shell currently being filled with satellites at 550 km should provide complete worldwide coverage from bottom of Norway to New Zealand (+/- 56 degrees North), but they do require ground stations as you said.
However to link together all the continents there will need be some ground stations in the ocean, either on islands or floating platform/ships otherwise London can't talk to New York. Nobody cares about covering literally the entire ocean with ground stations though. The 550 km orbit satellites has coverage area about 940 km wide, which would cover most of Iceland from a ground station based in England (ignoring Iceland being too high latitude). They would also make sure all of the popular transatlantic/pacific airplane routes have full coverage since that's one of their target markets. But yeah, most of the ocean would still end up left uncovered for at least another 5-10 years.
I've heard the idea of using ship's crossing with technology onboard as relays. I don't know how that will work though as of course it requires vessels to be constantly in those areas with the right equipment.
Currently the Geo satellites only give small amounts of bandwidth on Atlantic crossings so any improvement on that would be welcomed by Starlink.
There'll be a network of floating ground stations on supertankers and liners. I doubt there'll be any gaps.
The sats have interconnectivity via laser. It's not going to be activated for awhile yet, but not a decade from what the engineer at SpaceX say just 2 or 3. But it negates ground stations across oceans completely as said in the vid.
Starlink satellites relay data through each other to the nearest ground link.
My favorite service call was to climb up and take the cover off to unwind a dish. While at anchor, yachts would slowly rotate with tides and currents while the dish maintained tracking. When the dish reached the limit (+/- 3 rotations?), it would shut down. I'm guessing modern trackers would have remote and automatic reset functions which don't require removing the lid 😅
For lower orbit satellites like Starlink and OneWeb (with the UK leading a rescue) can use electronic aerials. They're just a flat horizontal panel that doesn't move. They are electronically 'aimed' at where the satellite is.
Those progressed into automatically unwinding antennas. Now we have unlimited Azimuth due to the use of rotary joints and power rings.
@@NeoMK Are there optical rotary joints? I suspect they might be faster than the ones made from copper and electrum.
@@jannikheidemann3805 No, everything is shielded copper basically. It's all LBand BDE and ADE and the rotary joint carries DC to power the LNB. The power ring carries the 220VAC.
Oh boy did the predictions about Starlink were off. 10 years he said, and in less than 4 years Starlink already revolutionized the maritime internet, not only because vessels using it but also pressuring the prices down. Never underestimate a bunch of math and engineering geniuses backed by a "total commitment or dead " billionaire. He has a new video, excellent as always, and clearly nobody can blame him, many were saying it would not work, ever, including people that are "experts at talking about space stuff"
It's easy to point out things after the fact. As the time of filming that was the state of Starlink. And we have done updated videos since then.
A solution, or base idea of a solution, if all vessels (Trans Atlantic certified at least, including yachts, cruise ships, cargo vessels) could all have an antenna to relay the information. Instead of a satellite being in space, the 'satellite' would be an antenna on every vessel.
This would work in the same way repeaters work with Amateur Radio. The signal would keep getting repeated from vessel to vessel til it reached the land based station where it would connect to landline internet.
APRS in amateur radio works this way as well. It sends the signal from repeater to repeater to repeater.
Radio signals travel at the speed of light. Talking on HF frequency from Chicago to Europe is instant. I think they could explore this idea for maritime vessels. It'd be a heckuva lot cheaper than $900,000/yr!
Excellent video!!
It should at least be enough for E-Mails and phone calls.
VSAT sounds like they came up with the acronym they liked before they worked out a plausible meaning for those letters
That's called a Bacronym. You start with the acronym and then work back.
Nice to see you back and in good health . When I get my super yacht there will be no internet , you think am paying them prices for the crew to play angry birds 😂
I focus on telecom strategy... And I have to admit that you have explained the concepts very well.
Iridium satellites have being doing inter-satellite links via Ka band for years. Starlink will have it's Ka band or Laser inter-satellite links working fairly shortly...
Well done very informative, those internet prices are just out of this world(literally)!
Excellent narrative. Very informative. It shows that you put in some research. Thank you.
I really enjoy your channel. This episode was very informative as well as being dirt easy for anyone to comprehend. Thank you so much.
All these years I have been saying, "mega'bytes" instead of "mega'BITS," and not once has anyone corrected me.
I learnt a lot today!
There are both megabytes and megabits, eight bits make a byte. But comm speeds are measured in bits, because the comm protocols carry overhead of various levels, so there’s no direct one-to-one correspondence between a raw data connection’s speed in bits per second, and the resulting user-facing payload transmission (usually measured) in bytes.
So you transfer files having a certain number of bytes over a comm link with a speeds measured in bits per second, but you can’t just use a factor of eight to calculate transmission times, due to protocol overhead (handshakes, routing, checksums, etc.) which eats up valuable bits…
In short: if you’re talking about file sizes it’s usually megaBYTES, if it’s transmission speeds it’s usually megaBITS/s, but theoretically one can use them interchangeably, provided one uses the proper conversion factor.
Now, to make it more complicated: in infinite wisdom (sarcasm) kilo, mega, etc. used to be base-2 derived, so a kilobyte weren’t 1000 bytes, but 1024 (2^10) bytes. Mega was 2^20 thus 1048576 not 1000000, etc.
Marketing people realized, that lowered the numbers, and switched to base 10, thus kilobytes are now 1000 bytes, no longer 1024, etc. Starting around the year 2000, a standard was passed much to the liking of the marketing folks, and thus…
The old base-2 units are still in use, sometimes by their old names, sometimes by their new fangled names. So the old Mbit is now the MiBit (pronounced mebibit) (2^20 bits), while the new Mbit (megabit) is now officially simply 1000000 bits.
So, there could also be data rates reported as “mebibit per second”, and if you don’t know about this mess, you might just think someone has a speech impediment…
Confusing enough? 🤷🏻♂️
Very good video. Great explanation.
Remember most of us have been on boats but not a super yacht. Lol
Thought I already knew a lot about this topic, but guess not. Thanks for all of the fascinating info! Love these technical videos. Perhaps a topic for a future video is the difference between the tech for most regions vs. communications tech for polar regions? Actually, would be cool to just hear about general tech (machinery, navigation, hull construction, etc.) required for polar exploration. Thanks again!
Polar regions must use MEO and LEO satellites. GEO sats will not work.
VSAT = Very Small Aperture Terminal. That was an easy one (okay, yeah, I'm a telecom geek). Thanks for doing this video, very well done. I'd like to see you dissect the antenna array of a megayacht like Flying Fox and explain why some of the antennas are so large. My understanding is the 3+ meter monsters will give you at least some coverage at extreme latitudes both north and south. Are those the dual C & Ku band VSAT or are they TV antennas?
I made a video about flying fox a while back and I talk about the domes. There’s a link in this video
The large antennas 96in. to 144in. are C-band. The 40in. to 60in. are Ku band. The larger the reflector the higher the gain. The higher the frequency the more the atmosphere attenuates the signal. Domes do not contain arrays, just a parabolic reflector that tracks the satellite and feeds the HF signal into the very small aperture that then down converts the HF into L-band. The motion and control for the antenna is MUXED or multiplexed onto the receive cable of the antenna. The transmit just carries the tx and sometimes voltage to power the BUC or transmitter. Musk satellites will utilize phased array antennas which have a much lower gain than a parabolic reflector and rain fade will be even greater than on a Ku.
Cross-links have been in use for decades - the US military on MILSTAR and AEHF; commercially on Iridium (launched in 1999); and more recently by the Europeans. Starlink purportedly to host cross-links much sooner than 2027, and Jeff Bezo's Kuiper satellite network, plus Telesat's LEO network all have baselined cross-links. In fact there are about 10 major constellations being built for broadband, so will have plenty of choices (of course, not all will succeed). Interestingly, the short video segment within this video shows traffic being routed between NY and London, which uses cross-links (notice how the redlines changed direction as the satellites moved in orbit)? Good video - thanks for producing.
Here, the most common for moorage clients, you have to have an account with ShawGo WiFi to have internet access, as well as the wired connection options ( local service provider accounts required ). Shaw Cable clients have a ShawGo Wifi account included, if you just want the wifi account I think it is a fairly cheap $5 or $10 a month in Canadian dollars ( 35-40% less in US dollars )
One sat network that even has polar region coverage is iridium, their satellites are not in geosynchronous orbits, instead they orbit lower and the equipment on board has to switch rapidly between satellites. They have a higher number of satellites so you should have 2 or 3 available at any time although in areas like the Norwegian Fiords (sp?) the high cliffs can block signal. The same land blocking signal can happen here in the PNW / Inside passage.
This area also has limited cellular coverage with a large percentage of the cruising area having no cellular signal.
Always great videos.. chapeau
Always enjoy your videos.. thsnkyou
Welcome back to the UK too 😁
Update - Starlink are already beginning to launch new version satellites with satellite - satellite laser communication between them - the future of global internet coverage is much closer than you think. Of course the priority is to scale to the land based populations and these can be served with ground based relay stations.
This was the very best internet ship video I sawZ none of the rest even close
I made an updated one talking about Starlink.
2022 and Starlink is HERE! And are able to communicate with each other via lasers.
Geostationary satellites from Inmarsat are okay, so GMDSS runs over there.
What do you think of iridium? They use LEO satellites at an altitude of around 780 km, even over the poles.
Starlink is just another provider and with this amount of sheet metal that Starlink shoots up into orbit, it affects other, established providers and wastes valuable resources!
Great videos and great contents, I like your work. 👍👍👍
Iridium is pretty outdated compared to Starlink. It uses very large/heavy/expensive satellites that have limited bandwidth. Iridium service is expensive and relatively slow because of this. Starlink is using much smaller/lighter/cheaper satellites (they can launch 60 at a time) with much more powerful hardware. Therefore, Starlink is likely going to be significantly faster, more affordable, and much more scalable compared to Iridium. Honestly, I think Iridium is going to be almost completely obsolete once Starlink is online. Iridium would still have a market near the poles, but that leaves them with a handful of customers paying for the entire infrastructure. I doubt that will be a viable business model in a few years.
Very low data throughput rates available on Iridium and it's also quite expensive for higher volumes of data. Much more so than GSO satellites.
One nice tidbit of information. SpaceX actually uses the same kind of gyro stabilized vsat antennas that are used on ships as uplink antennas for there ground stations. And a single superjacht permanently cruising in the middle of the Atlantic acting as a data relay would be enough to bridge the gap in coverage between Newfoundland and Ireland.
By the time I’ve got enough money to buy a yacht, the Starlink will be old news and something even better/cheaper/faster will have come along! Will be interesting to follow the progression of this technology
reply here when you get a yacht and i will too haha
As always very professionally delivered great information and very informative need to wait until I win the lottery to pay these exorbitant costs

Thank you for this video. Very instructive!
VSAT - Virgin Satellite Automatic Telapcation? Not sure
You are wearing the coolest shirt I have ever seen. I need one.
Greetings from Colorado! Lovely piece. Yours is a primary emotional resource/outlet to which I turn for relief when the enTIRE news universe seems dark to blackout. The Donald. Covid. Black lives. Veterans suiciding to the tune of 22 per DAY! 49 shootings in SCOOLS in 2919 in US... on and on AND ON!
Until I get to sea and visit your life which you share with a calm and erudite voice. Thanks, brother
Sounds like code, care to decode? I have been coded to be a good listener.
Many of those shootings were not in schools. The press includes ANY gun event within a mile of a school in that number. Some of them were BB guns where one person accidentally shot another with it and it was almost a mile from the school and the injury was VERY minor. The press LOVES to inflate those numbers to make it look like we in the US are a bunch of crazed gun nuts. So this number is not accurate at all. No offense to you.
Also, military personnel do NOT suicide at a rate of 22 per day. Not even close. The current suicide rate per month is 26. So that's less than one per day. ANY number of suicides is terrible, but your number claim is way, way off. The current rate is calculated by a rate per 100,000 military personnel. There are right at 1,300,000 personnel in the US military. And the current suicide rate per year is 24.8 per 100,000, on average. So, you multiply 24.8 times 13 and you get 322. Divide that by 365, and you get less than one per day. Please do a bit of research before posting in regard to hot-button topics.
I just don't like talking about such things here, anyway, because like you said, this is a place to escape all of that. But I had to correct those numbers with some facts.
@@CivilEngineerWroxton The guy is too emotional.
@@CivilEngineerWroxton And maybe you should concentrate on reading comprehension. He said veterans not military personnel.
You sir are a most knowledgeable man
Another great video with lots of interesting and informative information. I love your sense of humour. 👍👍
Well done, thank you for this detail!
Nice vide like always. I like the t-shirt :)
Always enjoy your videos.. Take care and stay safe.
Very informative. When I get my mega yacht it will come in handy. I enjoy your channel.
If I were designing a Worldwide Satellite Network. My first group of satellites would be the space to ground satellites.
SpaceX has a habit of constantly changing the design of *EVERYTHING.* Which is pretty interesting.
I wish I could remember the video I saw when a representative from SpaceX (probably an engineer) was discussing the first 60 (don't quote me on the number) wouldn't be able to communicate with each other.
But the follow on satellites would. And that there will be at least 2 altitudes the satellites will be flying in. In addition to all the orbital planes they will be using.
Of course this is all subject to change....
This is SpaceX after all. 😂
Great video.
As usual great video. That must be why boats like to stay near shore, at least one of the reasons. What about emergency communications?
They always have redundant communications, VSAT, INMARSAT, FLEET BROADBAND and finally VHF and EPIRB.
Excellent - all the info you wanted to know including interesting tangents that were brief. Pleasant voice. I feel like I got the truth from an "insider's" point of view.
Thanks for that - just shows how the other half live.
The last thing I would want to do on one of these yachts , would be surf the internet.
How about Iridium? They kind of support communication between satellites ?
Very interesting... THANKS for sharing!
I just got a RUclips connection to your video lol. Very good vid and I will definitely watch more. Although its already a few months back since you posted this (and might have already answered it in one of your next vids which I'm catching up too), I wonder if the Starlink project satellites will interfere with the VSAT? Will they block/interfere with signals to higher orbit satellites? i.e. will a VSAT system become obsolete in the near future?
Great job explaining ...I get that Mbps and Mbps mixed up, I can't imagine why.
Isn't bit shortened to b and byte shortened to B?
The difference is the capitalization, if I am not misinformed.
Best described subject I have seen for ages. Can you now do one on how Decca Nav works. Regards john
Check out my latest video on the subject of Starlink. ruclips.net/video/uh_cJK3A6kI/видео.html
Starlink may be a great option for places like the Caribbean/ Mediterranean or other areas with lots of islands. Not great on long oceanic passages but for a lot of areas where people are cruising still probably will be viable resource to throw into the mix.
The update to this would make this not true. Starlink's issue is node saturation... basically, it's gonna be great for areas with low usage and mediocre or worse in densely populated areas... so the BEST uses for Starlink will be rural areas and at sea.
internet vs satellite.
i had a minute conversation on the 31st of December with my girlfriend at the time to wish her a happy new year from Antibes to Portugal from a motor yacht. . and it was on a sat phone in 2001 and it cost almost as much as i as got paid for the day. from a motor yacht to a land line.
so that was the cutting edge of communication 21 years ago.
Another interesting vlog,when I get my yacht I will be head hunting you.
It had better be a big one then, he's said a few times that he only works on 100m+ boats
Great video mate
Fantastically well explained. There are more technologies, there are also cheaper packages that you could opt for .. but .. and this is the problem: these yachts move about. So it's always the issue of weighing up hassle vs cost. The golden middle way is the solution. And yes .. roaming connectivity at sea is most certainly one of the most pricey issues you can run into.
00:20 In Longmont (northwest of Denver) 1GB (price guaranteed for life) costs US$59.99 It is a public utility so the address assured the rate and I am assured the rate no matter where I live in Longmont
Thank you for a lot of good easy to understand technical information. Awesome vlog. I was thought it’s created by a professional. 👍
I remember a few summers back that my friends and myself started arguing about internet on your boat. Where we were at was our home Waters of Maryland right next to the naval academy in Annapolis. It started off with who has a better cell phone service on the water and then we change that subject to how is the internet. Of course where we were at everybody had great service. My wife and myself started talking about how when we go on longer trips and we are in the middle of the Atlantic ocean that other than my emergency satellite phone that we do not have internet service most of the trip. Then that is when everyone started telling me that I can get a satellite dish and get internet and TV service anywhere. I explained to them TV service is different and that internet on a boat for one month was over $10,000. Everyone started arguing and telling me I was crazy that there's no way that could be right. So I went ahead and pulled up all the information on my laptop and showed everybody. Then the conversation changed to why would you care you have the money. That was a whole new argument about how you keep your money and not wasting money on ridiculous things.
I enjoyed your video and look forward to the next one.
.
Your friends are the future bankrupt lottery winners because they have no real concept of money and how not to throw it all away.
No one needs that much money and 'stuff' just self indulgence and greed.
15:22 in my American mind went" why can't you use a basketball as an example or a socce... oh FOOTBALL" words lol. Hahahaha
As usual. A great video. Very informative
There was just an update where they tested the Sat to Sat communication via laser, so time to update. Great videos
I was waiting for you to talk about starlink and maritime Internet. It will need a few years to launch all the starlink satelites. What I'm worried about is people who will be watching videos while walking on the streets.
People can already watch videos while walking on the streets. 4G cellular has plenty of bandwidth for video. Starlink requires a transceiver the size of a pizza box so I don't think people are going to be bring Starlink connections on their person.
@@CL-gq3no I was thinking it would lower 4g Internet prices so a lot of people would actually use it to watch videos while walking. Cuz people in some countries can't afford wasting too much data. I hope you get what I'm trying to say. and about the 2nd thing you said, thanks for the info about how starlink works.
As far as I understood, Starlink is stationary only. Check out Jeff Gerling’s video about it. He couldn’t even install his dish (registered to his home) to his sister’s home, for several reasons.
Interesting video . Nice to see our price list in it :) It has been improved since .
Regarding starlink beyond the technology the business model is maybe not sustainable. The expectation to get cheaper internet is not going to be matched . By the way they still don’t have the approval to operate on mobility neither an antenna for mobile platforms
Wifi and cable in the harbour sounding like a security nightmare
With out a (repeter) switch the max lengh is 100 meters, the best cable ethernet is Cat6 you can use 1.5Gb.
the first launch of 60 was unable to communicate with each other and pass the information along but the current launches are fully functional. their current plan only requires 4000 satellites but they have fcc clearance to launch 40k most likely they will never reach this number. although their curent plan does not reach the poles and i do not think it reaches Alaska at all so in those situations vsat is till the only way to go. i am unsure if they have plans to ever cover the poles but i think it is likely as they have a large market if they can get coverage to the uk
If I remember they ended up switching from laser to radio. But ya the full production models chat with each other.
I just watched a video that Starlink launched a Maritime section. Just enter the shipping address to check for coverage.
Very interesting as always. I had thought that Starlink would be a solution but had not taken the earth stations into account. I wouldn't sell Musk short on this too soon though, if he can land used rockets on a ghost ship in the ocean, he may see the need for a solution here sooner than later.
It will get done, no doubt with that, but communications between satelites are much more difficult than may seem. To understand why you need to know how TCP/IP protocol works (the connection protocol of internet).
To put it simple: Every device connected to the network can be considered a "node" and every package of data you send or receive through internet travels between several nodes before reaching its destination. The routing of the package is set in every node individually, there is no default route set for a certain package and every package is treated independently to other packages. Every node that receives the pakage and has to resend it to another node in order to reach the final destination; decides which will be the next node the package will be sent to. That decision is made based on something called "routing tables" and the IP adress of the final destination of the package (which is written as part of the data package). Every new node connected to the network, first thing it does is broadcast its IP adress and receives from the other nodes it is connected to their IP adresses (which will create the routing table on the new connected node).
That is "easy" when nodes are constantly connected to the same ones and are stationary, so they don't have to change the routing.
For starlink that is much more difficult as, unlike geostationary satellites they have to keep changing land bases constantly and therefore their routing tables, if you add that to the problem of creationg new connections with new satellites aswell it get so difficult, also because even 2 satellites can be "quite close" (astronomically speaking) one to another, they move at about 7 km/s around the earth, and their relative position one to another is changing constantly. Keep in mind that satellite antenas are highly directional to focus power, but that means that they must be pretty much pointing one to another directly to get any signal at all..
Of course you could make omni-directional antenas and receivers which would theorically avoid those problems (directivity and effective area of reception are inversally proportioned and it's a constant that depends only on the wavelenght of the signal, actually is Area/Directivity = [(wavelength)^2]/(4*pi)), but those satellites are not close enough one to another to be able to use omni-directional anthenas without wasting much more energy through signal sent to useless directions than what the satellite is capable of generating through solar panels.
All that without getting into other stuff like polarization, clockwise or anti-clockwise...
Sorry for the long message, I tried to simplify it without making horrendous mistakes due to the fact of oversimplifying things. But trust me when I say that I could easily write a PDF of over 20 pages just to explain how things actually work for people who already have a notion of everything I would be talking about.
Thanks Javier!!
Not sure I completely understand what you were explaining, but I'm very interested in getting a "fix" for the high cost of slow speed Internet at sea.
I'll watch for your 20-pg PDF and give it to someone who understands it better!! Cheers.
@@kistosable important point. But there's no reason at all to use IP protocol. The internet backbone uses SONET frames, which encapsulates IP packets. In your house you probably use ethernet packets which encapsulate IP packets. In other words you're free to use what works best.
All the routing decisions could be done at the ground station prior to the first uplink. I would be interested to learn how multi-satellite routing actually works.
As you say, it's very much more complex than the single-satellite mode being tested now.
@@henryD9363 You are going deeper, I said I wasn't explaining the full thing because as I said, if we have to explain how the whole www works in full detail we can spend here hours writing things most people wouldn't comprehend.
You can separate the network into two different ones: the one done on earth and the one done on LEO satellites, but still, the routing protocol should consider the constant changes in position between the two "subnetworks" and the main issue remains.
The issue is not establishing a link between earth and a satellite nor the protocols we use for communications. The issue is that LEO satellites move relative to the ground level, and they do fast, so the calibration of the routing must be performed constantly and with high precision as the anthenas used on satellites are highly directive ( as the acronym VSAT suggest). But I'm glad that actually someone could understand my comment. I did my job nice then :). Salutes!
Liked the fly over of the Flying Fox. BTW... in the mid 2000's 45Mbs of dedicated VSAT ran about $150,000 / mo..... so... looks like we are making progress on pricing.. 🤣
VSAT (Very Small Aperture Terminal) is a satellite communications system that serves home and business users. A VSAT end user needs a box that interfaces between the user's computer and an outside antenna with a transceiver. The tranceiver receives or sends a signal to a satellite transponder in the sky.
Why did you copy and paste this? The details are in the video.
very well explained especially the starlink part , thanks. are you currently working as a captain ? are you able to say any of the yachts you have captained in the past ? all the best
I’m not a captain. I’m in engineering department.
Good video. Very informative. That's why I like this channel.
My suggestion to billionaires: make platforms(like oil rig platform), with cell towers. Start planting them in the well traveled areas.
Solar panels, cell tower, floating platforms. Make it happen. If you care.
I love your podcast.
For Starlink, just put a small land stations on the, Yachts, Ocean liner, Cruise Ships. Maybe.
The land stations are what connect the satellite network to the rest of the internet. If you put them on anything mobile you would be right back where you started with no internet. It's like saying "put your home router in your car so you'll have mobile internet." Clearly that won't work as once you unplug it from the home's wired internet connection.
Wow, very nice. Thank you.
Actually, Starlink satellites will communicate via laser, thus radically reducing the number of land terminals required. Please refer to Spacex for correct info.
The info in this video is correct. This video was produced in July 2020. Everything said was accurate at the time. And the lasers still don’t work. The satellites still cannot transmit data through each other.
Holy moly - didn't know that VSAT is such expensive - guess I stay with 4G on my vessel 😜
Thx for the interesting info 👍😊
Very interesting and full of useful informations. Thank you!
Great video, question: Do they have separate networks for crew so they don’t spunk it all on Netflix etc?
Oh yes
Yep, the crew is very limited if guests or owners are on board. But if not, every night the highest BW utilization is to porn sites.
