- Before Christmas, I got a package from Lacuna. It contains this small module that should be capable of transmitting sensor data to a LoRa satellite and last for a few months with this battery. After my last experience with FossaSat-1, I am skeptical. Do you want to accompany me on the journey?
We all were disappointed when FossaSat-1 did not work. I would have loved to transfer a LoRa message from a 20 dollar sensor node via satellite to my computer before the turn of the decade. FossaSat-1 showed that many problems have to be solved before we can transfer a message via satellite. But let’s have a quick look at who sent me this package.

Congrats on getting the Lora satellite message, happy 2020 :-)
Happy 2020 to you, too!
this is amazing. I've secretly being waiting for something like this to kickstart a new age of amateur radio transmission.
We will see how it will continue... interesting times.
I love how it combines all Maker passions - the hardware side, software ingenuity, radio wireless comms using digital protocols, and especially outer space tech - its a Maker tour de force.
Even something like a dedicated repeater has to address having a receiving antenna and transmitting antenna operating in close physical proximity - those industrial grade repeater installations up on mountain tops are really something - now condense that concept down into a tiny, affordable LoRa gadget - couple to a solar panel and appropriate battery, a weather proof enclosure - then spread them across the land on rooftops like a modern day Johnny Appleseed planting apple trees across a continent
@@TheSulross yes definitely your right, i think about all of our radiotower they are just carrying wireless data connection .. and most have still power and space for some ham "gadgets"
Congrats for succeding with your first message to space Andreas. And for everybody, Happy new year! Feliz 2020!
Happy 2020 to you, too!
Excellent video, incredible that it is possible for we makers to communicate globally... Happy 2020 !
And with so small power and antennas... Happy 2020 to you, too!
Makers have been able to do this for years, but now it is consumer-off-the-shelf.
What is approximate cost per message?
I do not know the pricing model yet. You have to ask them. But maybe they still have to decide...
Andreas Spiess i think it will be free by fossasat
A some teams want to use IOTA crypto to pay for messages without transaction fees so probably about 1¢ for 10 MB of data
@@yagoa That kind of cost makes Lora even more appeling to the layman.
@@AlanMedina314 that is more the immutable storage part, using bitcoin is more like 100$
Thank you Andreas! Congratulations in your success of sending and receiving a message before 2020. Thanks for taking me on your quest too, it's appreciated more than you realize.
You are welcome. I also was glad to get it done this year...
Amazing results - Congrats on the excellent video
Thank you!
Your videos are a sunday morning hilight for me. Keep them coming. All the best for the new decade.
Thank you! And a Happy New Year for you, too.
Apparently LoRA space race has begun.. amazing how rapidly lora grew and now reached space.
2020 is going to be interesting:).
Alles gut... und danke Andreas!
You are welcome! The last few year were quite interesting for the Maker community...
Andreas is better than Netflix! Thanks for sharing this adventure. All the best for 2020.
Thank you. But if you ask my wife, she still prefers Netflix. Good for me. Then I have time for my projects;-)
Congratulation on your 2019 success. Continued wishes for further 2020 success Andreas! Amazing times.
You are right! I also wish you a Happy 2020!
And a happy 2020 to you Andreas. Interesting LoRa times ahead.
I also wish you a Happy 2020!
Great video Andreas .... Congratulations Lacuna Space team... This will be breakthrough in LPWAN use case deployments...
It is for special cases only and we will see if they will get enough paying customers. I wish them the best.
Finally, it works ✨✨. I just can't imagine the joy you felt receiving the first message.
Wish you a Very Happy New Year 2020.
I also wish you a happy and successful 2020!
Again, really interesting. The next decade sure looks promising when it comes to space, sensors and IoT. Happy 2020 !
Happy 2020 for you, too!
Cool tech! Und einen guten Rutsch Andreas!!!
Ich wünsche dir ebenfallls einen guten Rutsch!
LoRa became a 1960' thriller series, I wait for the next episode.
Lately I had a lot of LoRa. Now it is time for something else...
Yeah, i saw the presentation of the sx1262, like it was some sort a miracle, now I'm little disappointed with it. Thanks for the first insights Herr Spiess! I wish for you and your family happy new year, good health, and many more interesting videos! Best regards
I also wish you a Happy New Year!
Happy 2020 and keep those excellent videos rolling in.
I could see so many applications for this in research. Being able to put inexpensive sensors in extremely remote locations, and have them call home only every so often, without need for expensive sat phone hardware would be amazing.
They have now already three satellites and I get more than one pass per day.
Happy 2020 for you too !!!
You might know you vídeos are very well done and contribut a lot for a new technology point of view perspective.
Congrats!!!!
Thank you. And a happy 2020 to you, too!
Hi Andreas! Any updates on this? It's been about 3 years and I'd love to be able to buy one of these Lacuna modules or something.
I lost contact with Lacuna. So you have to ask them directly.
I love using my satellite whiteout paying 😊😊 is really possible and I truste that's where am living I can hatch stuff without getting problem ! I'm drawing a sketch by watching a lot of video in RUclips, but you are the best person who I wish to see on day ! Thank you so much Mr Andreas
You never know...
@@AndreasSpiess knows abouts ?
You will see me one day...
Hi Andreas,
awesome video as usual. It will for sure be an interesting coming decade for us makers.
We will see if this channel will be around in 2030 and when, which topics are covered ;-)
Happy 2020 from India. Keep on showing excellent and very informative videos
Thank you. Happy 2020 to you, too!
Congratulations on your LoRa communication to a satellite, again an educational video
Thank you. Glad you like it.
Well done Andreas! 👏👏👏 A new era is born!
Let's hope they will find enough paying customers...
@@AndreasSpiess this is cutting edge at the moment, but all of the technologies involved are mature enough - this is the 21st C equivalent of Alexander Graham Bell putting extant components together to make something new from them. We can't yet dream of what they will be needed for, but tiny data from connected sensors is already becoming more widespread, and whether it is sheep counting in the remote Australian outback to drift experiments in the middle of the Atlantic ocean, someone somewhere will need it!
I wish you a very happy 2020. Thanks for sharing !
You are welcome. And a happy 2020 for you, too!
This is incredible. What's the forecasted price of the hardware (you said $20 but surely the antenna will increase it) and data link?
I do not have an update on this project. You have to ask Lacuna.
Well done Andreas! Wishing you and your family a prosperous and Happy New Year!
Thank you. I wish you and your family a Happy 2020, too!
I been looking at getting started with Lora transmission and I think this video has made it more appeling.
To think that sattellate data transfer can be achived through a simple Lora node is extremely interesting.
Glad you liked it!
Fantastic! Well done Andreas!
Thank you!
Another informative video, thank you Andreas. Best wishes for 2020
Thank you. A Happy new Year for you, too!
Interesting video and at the same time promising technology!!! This new approach really opens the door to many new applications/opportunities. Happy holidays to all! Happy new year Andreas!
Happy New Year to you, too!
It´s good to know this technology works!!. It will inprove telemetry from remote hydro and pluvio stations, and other applications too. Good things are comming. Congratulations for your work and thank you for sharing your results. Happy New 2020!!
You are welcome and Happy 2020 to you, too!
yes, this technology is amazing, would be very cool if the space technology will skyrock in 2020
Not everybody seems to be happy with this fact ;-)
@@AndreasSpiess well, no one could stop the progress ;-) I'm dreaming about a world where everyone could launch his own satellite for under $1000 and use it, like having a PC. Space technology boom could be the next step after informational technology boom which we've experience for the past few decades. Actually this is already happening, Elon Musk is launching payloads into space very very cheap compared to others, also do not forget about the Starlink project.
@@meteor8076 yeah but SHOULD you be able to? Space is already crowed with space debris and yunk..if you put one up, you can't take it down again (the small ones)
Got it working just before 2019 expired! Outstanding! How can we reproduce this?
Because I am an early tester you have to wait a little till the service is fully operating...
Happy New Year ! And I am happy too that lora works with satellites.
Happy New Year, too!
Happy new year Andreas Spiess!! Please keep making those awesome videos..
Thank you. Happy 2020 to you, too!
Sir can I use LoRa RFM95 for my cubesat (in 250kms altitude), to Tx & Rx data? I mean is it really possible with the help of LoRa? Please help me Sir.
Wishing you a happy and prosperous New Year.
I also wish you a happy 2020!
Lovely details about this project
:-)
Danke. Einen guten Rutsch!
Bitte, gern geschehen. Ich hab gedacht dass ich das dieses Jahr noch bringen muss. Ich wünsche ebenfalls einen guten Rutsch!
Nice to see it works.
Yes, that is what I thought, too.
thanks i will continue to look this solution for my boat while at sea to send daily message my position and status eg including sinking SOS etc as back up to eperb SOS solutions
Interesting concept.
Wow!
I am amazed.
This is good stuff.
Great video as always. Happy New Year and thank you.
I wish you a Happy New Year, too!
Fantastic athivement
A Happy New Year to you too
Thanks for sharing
You are welcome. A Happy 2020 for you, too. And thank you for your many comments!
This is so exciting.
True!
Is Lacuna available to the public yet? Seems more like they're partnered with enterprises rather than making themselves accessible to us makers. Congrats on this achievement, it's amazing the things you are accomplishing and publishing to RUclips so regularly. I'm in awe.
@LabCat nothing ever is, but they don't provide a way to take my money from what I can see.
For the moment I do not know their pricing policy. I made this video because for me, the proof that lora can be used in space was relevant. As I mentioned, maybe most makers will not use Lacuna's services we still hope for Fossasat, for example...
The guy with the swiss accent is the best.
:-)
Thank you Andreas for all the great stuff you do and share.
Happy 2020 !
A guy with a french accent ;-)
You are welcome and Happy 2020 for you, too
Love your videos Andreas. But enough LoRa for now! 😉 A nice home automation type project would be good 👍
ruclips.net/channel/UCLecVrux63S6aYiErxdiy4wfeatured
You are right. But sometimes I am taken away by interesting things. And they happened now... We will see what next topics are on the list ;-)
I was wondering about polarization of the signal. The antenna on the satellite suggests linear polarization (simple dipole). If this is true, then won't you experience an additional loss with mis-matched polarizations - or are you using a circular polarized antenna and accepting the loss? I looked on the fossasat page for electrical design info, but didn't see anything related to this.
I accept the loss. A circular antenna would also not be the solution if the transmitter is linear.
This is marvellous. Would be very useful on a remote trip to be able to send a brief message (e.g. gps position) once a day.
There are a few such scenarios. For wild animals, for example...
Really it's a great success. This will break distance barrier for devices. One query, how much time satellite will take to relay back the received data?
It depends where the next ground station is. Here it was a few minutes. I assume they have a ground station in Holland or in the UK
Lacuna lora module can be replaced by any other Lora module? i don't have that gadget available in my country so i was wondering if it can be replaced by any?
Thank you
No. And you need a contract with them. They are a commercial company.
There will be more Amateur LoRa satellites for sure
We will see. But the technology is quite cheap and the huge link budget compelling for low power nodes.
@@AndreasSpiess It is too compelling to ignore. Amateurs have some very good weak signal modes of their own, but no ten dollar complete solutions like LoRa.
Just courious, to me the most useful thing about lora is for a SHIFT synareo. Be that a local event like a tornado or a world wide event like the end of the world as we know it. In such an event services like internet may not be available. Is there a way to program that thing to find the path and timings of the satellite?
www.spaceref.com/news/viewpr.html?pid=54397
This got me thinking that considering what a bunch of boys without background and very little money have done I think is remarkable, uh?
No point of comparison, but still there. I wish in the future Fossasat have more support and stay free (and Everis the only supporter stays with them)
I think, for Fossasat you are right. Lacuna on the other hand has a very experienced crew...
Dear Andreas, I'm very interested with your explained .Where I can get to purchase Lacuna module?
You have to ask the company if they are fully operational now and where they sell the modules.
@@AndreasSpiess Where did you bought the Lacuna module ? I mean the online shope site.
@@supriyono2723 I was a beta tester
Happy 2020, from the guy with the American Southern accent! :-)
A Happy 2020 to you, too!
@ Andreas Spiess A great work sir. A big motivation for young Engineers to do research. I have a question can we achieve direct access to the geo satellites with this ? Is there any possibilities can you point out . Thankyou in advance . Have a great day God bless
No. You have to use other protocols. Maybe you watch my QO-100 video series
@@AndreasSpiess MAC layer protocols or any other protocol sir . Can you Exactly specify what does it mean . Thankyou in Advance .
Love it ! looking to make my graduate project on this
Watch the timing. The system is in test phase for the moment.
fosa sat1 seems was working a day after your video
It still works. But not for the intended purpose because the antenna is not deployed. You need very big antennas and high power to reach it.
At the higher ISM (900 vs. 433) frequencies, doppler shift will be a bigger issue, especially at lower apparent elevations when the path length is changing more rapidly. I wonder if the space segment receivers have any special tweaks to deal with this? I'm not familiar enough with the LoRa waveform/modulation envelope to know if it would be particular sensitive or tolerant of doppler shift. Thanks again for the very interesting video!
LoRa seems to be well suited for doppler effect related problems because of its chirp technology. And I know from Thomas that they worked with Semtech on this problem.
Cool finger pointer 👆😆
Thank you!
Cool video, may I know if I can get some message from satellite? I have a pair of 915 MHz, is there any high gain antenna in the market? Thx
You have to have a contract with Lacuna for this project. Maybe you watch my video about TinyGS?
I'd like to know your opinion on this: would you say it is realistic to send/receive a message to the satellite from an underground car park?
You need a line of sight between the device and the satellite
how we can send a packet on LoRa to a CubeSat and Receive it at the base station? I look for Tiny GS but it is just for receiving from Satellite. Can you lead me in the right direction?
Cuttently I only know of commercial satellites that act as relays.
is it possible to send or receive a video package through lora module? or should i stick to the xbee?
LoRa is very slow and mainly made for sensor data. But it can hundreds of km range. So it is very different than Xbee.
Technical question : does the decade start at year xyz0 or xyz1 ?Anyway, the year starts on Januray 1rst ! So happy new year ;)
I do not care too much about the definition. For me it is this week ;-)
Decade ends Dec 31, 2019
perfect video.. thank you sir.
You are welcome!
Is there any chance left for FossatSat1 to become operational?
I do not know the details. But I assume it is like with crime: The chance to catch the thief reduces every day a little...
this is very interesting . i am a sailor. and any reasonably low cost coms with the outside world catch my attention. even if it is only for emergency beacon. the commercial ones are expensive
Its throughput is extremely small. Only for sensor data...
Waktu Telah Tiba....
untuk apa?
Can I transmit data with a normal Lora board or do I need to buy specialist equipment.
LoRa boards can transmit. But for satellites you need a Service agreement to use this function.
Your hilarious. At the end you said have a good 2020.
I had a good 2020. A lot of time for my projects ;-)
How will this topic aid a RC Plane that is using the .915 Frequency? I don't want to drop out of the sky with extra traffic?
I do not see a problem there becuause your signal will be stronger and the chance you use the same channel is small.
Andreas, almost 6 months! Any update?
You have to ask Lacuna. My groundstation still works.
Thks & Amazing but it would seem doing the signal processing via software or FPGA would be better than thru a CPU.
The LoRa modules still contain conventional receivers, not SDRs
Nicely done Andreas, where can one find the trajectory / Orbit info for Lacuna, cant find the register for it anywhere / Br Anders
I left a link in another comment.
@@AndreasSpiess Hi Again Andreas, tried to find the link, however dident find any references to the Lacuna sat anywhere, i want to track it and se when it´s over scandinavia, does it have another name within the space catalogue over sat´s? also, is the antenna in your setup right or lefthand polarized? BR / A
also is Lacunas gateway encrypted as of now in the test fase?
Toll dass es geklappt hat. Die Signalstärke oder die SNR wird zwar nicht angezeigt, aber intern sind diese sicherlich verfügbar. Was kommt beim Satelliten bei 600-400km Entfernung, Richtantenne und 100mW an, -140dB oder weniger? Wird beim Satelliten ein LNA mit Saw Filter eingesetzt für die Signaloptimierung? Wäre toll, wenn sie Mal ein Video dazu machen könnten, wie man sich ein lna+saw Filter für 868mhz löten kann. Würde ich gerne für Lora und flarm nutzen. Auf dem lokalen Markt gibt es kaum käufliches bzw preiswertes aber die Einzelteile sind verfügbar.
Ich weiss nicht wie der Emfänger aufgebaut ist. Hier gibt es einen 868MHz Filter, wenn man einen braucht: www.aliexpress.com/item/32854454729.html
@@AndreasSpiess merci, ja den kenne ich. Und den gibt's auch noch www.passion-radio.com/ism/868-saw-830.html aber 3dB Verlust finde ich nicht so ermutigend. Aktuell nutze ich den sdr RTL v3 Stick, aber ich werde evtl zur Sicherheit auf einen günstigeren stick wechseln oder den Antennenabstand vergrößern, da ich doch Sorge habe, dass der Eingang vom sdr kaputt geht durch den sehr nahen airband Sender...
Grüezi Andreas, Hast du schon was gehört von Opensource Zugang? Könntest du vielleicht die genutzte Arduino Libary Teilen?
Grüsse vom Bodensee
Lacuna ist ein kommerzielles Angebot und ich weiss nichts von einem Gratisservice. Es scheint schon so schwierig zu sein damit Geld zu verdienen ;-)
Is it important to use logic converters for communication between Arduino Uno and ESP8266, or a voltage divider would work?
Th ESP8266 is 5volts tolerant. You can connect it directly to the Arduino Uno

Sir, how can I contact Lacuna? I need to develop commercial nodes for a client, c
I assume they have an email address. I am not connected to them. lacuna.space/
Very interesting , l am following the LoRa progress ..but it is a sad 2020 for all of us. I had planned for a total eclipse of the sun in Chile on Dec 14 2020. Everything is gone.
For me the 2020 is ok. I had a lot of additional time for projects ;-) But my journey to the Pamir also was cancelled.
even some slow speed not 100% realtime APRS could help in case of stolen car, we have here in brazil in the outback huge areas without coverage of cell pager or whatever
I had some success with Apple trackers with our stolen bicycles (I made 2 short videos about it).
Thank you for the video. How can I set up my own system to transfer LoRa messages to the Lacuna satellite? How can I buy the same system you used in your video? Currently, I don't have any hardware at all, so I am looking at what to buy. Could you give me some links, please?
You have to contact Lacuna. I got a test unit from them.
Where did you get the example sketch from?
I am an early tester and got it directly from Thomas.
What is that tool to test antennas?
N1201SA vector impedance analyzer. He has a video describing it. Have a look. Great device.
Congratz! Thanks for sharing your knowledge :) question please : I would like to host my lorawan gateway to share an open network. Which equipment is a good starting point please? Thx
Loads of info on the TTN website under learn/gateways
Or my LoRa playlist.
Ive tried using SIM800 for data transfer but failed, I wonder if you have a 3G or 4G example , I want to send one per day single low res image across the telephome network from some woods to a web page with a data sim , eg 10MB / Yr ~ £5.
I abandones 3G technology. So I cannot help.
Hello guys, i would love some insight help on how could I start with satellite tracking/ communication over the ku band with an arduino board. is that possible? How could I make such a dish or what should I study to learn such aspects...
Maybe you watch my other satellite videos. There you find links.
@@AndreasSpiess Thank you!!!!!
Can you use this on a HELIUM HOTSPOT? CHOOSE THE SIZE OF THE MESSAGE? 👍
I do not think so.
I tried following the chatroom for the FOSSA-1. I never got a reply. Did the antenna finally deploy? Is it actually working? Thanks. This is all very exciting!
AFAIK the antenna did not deploy. Otherwise I would have used their satellite for my first message...
the future has (finally) arrived... Can't wait to try it
I did not want to wait to tell it to my viewers. I am an early tester, so you have to wait till the official launch of the service :-(
Love your videos and just subscribed. Have been learning more about Lora and you have been a great help in this journey. I'm trying to create my own project but atm I have a very basic question. Can we use other Satellites/ Gateways to get info about our devices. Like lets say I have 8 devices I want to track in another country and I want to see their location ( don't need live location) from an website/app.
As I said great channel and keep going.
The TTN network is global. As long as your LoRa signal can be received by a gateway, you will get the messages
Why do you have wireshark?
To look at network traffic
