Thank you SO much for describing the difference between single, float, and fix. This was a great video for a new user like me with the Emlid Reach units. We are connecting via bluetooth but this was so helpful to get me going. Thanks!
I love how he has RTK merch!!! Yessss! I am here because I work in Automotive DAQ hardware and need to learn more about RTK and how they could work together
Thank you for these videos, I graduate this year with a degree In GIS/Geomatics. Your videos reinforce my studies, they are not to elementary and not to complicated… great job
Great video. In the last video you briefly talked about fixed gnss reference points accessible to the public. In a future video can you expand on this subject?

Hello Rami, first of all thank you for all of your valuable video guides that you have been sharing with us. I personally have a question for you about indoor navigation solution in confined space. Please advise.
Thanks Rami! Super informative. Do you have to have a known survey monument or control point with coordinates to set up the base station to achieve high level of precision? Or can the base station be placed anywhere as long as it is fixed to achieve the same level of accuracy?
1. What is the maximum distance permitted between the rover and the base station? 2. Is a direct line of sight required between the base station and rover? Will this technology work in a forest where trees may obstruct signals? 3. You referenced a known monument base station longitude and latitude coordinate. If you are in a wilderness setting how is this point obtained? If you are in an urban setting, how is this point obtained?
Hi Rami, I’m wondering if you can help this enthusiast understand how you find the exact coordinates for a point for the base station or a total station when needed. It seems to me many total station operations you need exact coordinates of a point and for the base station you also need exact coordinates. It seems to me it’s a bit like the chicken and the egg situation. How do you find that exact coordinates of that first point? I’m from the U.K. not the US if that changes anything. Thank you.
Most governments have an open data portal or map where you can normally activate and deactivate layers, there should be all points (at least that one from the governments). Have a look for example in www data gov uk (urls do not work in yt), sometimes it also helps to go for a city data portal - or just ask a local surveyor
Could you please make a video of emlid base and rover, determining it's precision over a point. Ie record record one point several times under different weather conditions and different times of the day. And show us it's consistency I will be grateful
Hello, thanks to share all your knowledge! if there is no known point near the place we have to survey, how create a georeferenced landmark with the reach?
Depending on your location, you might find a geo-referenced point from hydrology department of your area, land survey companies near your location or a GTS benchmark. You can then use the baseline transfer to geo-reference your nearby point from the already existing geo-referenced point ( legs of transfer depend on the distance between both the points)
Great video! However, will the base lose its mobile connection when you're out in the field collecting coordinates with the rover? Basically will the hotspot range be a limitation, unless you have two smartphones to leave with the base and one to collect data on the rover?
Good day. With these receivers, the base will not be transmitting corrections via wifi. The corrections will be transmitted via built-in uhf radio (Lo-Ra) or the internet. If the latter is used then both the base & rover will need 2 separate connections to the internet. So the short answer is no - the hotspot range will not be a limitation
Rami, It’s my understanding that if you enter northing and easting values for your base station and want to layout points in NEZ that the emlid software will make these conversions automatically. Is this your understanding?
Good day, What was the maximum achievable distance between LoRa transivers during successful RTCM3 corrections forwarding with LoRa (8:36) ? Regards, AB
Is it possible to messure without without seeing the base? For example in the back of a building And second question Is the rover and base able to messure in a case rover has no connection to satalite? Maybe to get the hight of first floor in a building?
I’m struggling to understand just one thing… How could you know the coordenate of this point that you setup your base station if you “rent or buy” the RTK just for that reason? In my case i picked up some points using a total station, so the only reason im renting an RTK GPS is to reference a materialized point that i used as a base point for the total station. I know that in someplaces you have a geodesic mark, a fisical mark, that has already known coordinates. But in a case that you don’t have this, can you just set up your base station anywhere you want and start yours measurements? I hope you understand my question, English is not my home language 😂 thanks for now
Great information Rami, thank you for posting. I've been using the Emlid Rs2 for a while now over Lora radio. Do you have any videos on how to diagnose when your Base and Rover recievers lose fixed connection intermittently? For example, how do you know when it can be a simple fix like changing the frequencies or something where the only way to achive fix is to switch from Lora to NTRIP?
Can use multiple bases with one rover, as the rover may be obscured by obstruction to the line of sight between rover and base but possibly visible to another base? In addition, if the rover loses connection with the base what happens to the accuracy of the rover? does it just revert to the satellites GPS position
Hi, if I have not known point for Base. For example If I have to survey or topography in area where there is no known gcp point, how I can start. I have base and rover setup same like in this video. Regards.
Heyyy bro... please share more videos about RTK gnss...and i have a question... That you measured base height from ground to the pole of tribrach but in rover you measured the height from ground to rover's center... Why?...
please Rami, confirm your base height measurement, you measure to the antenna bottom, phase centre or to antenna top. I think each manufacturer always indicates that
Nice video it really help me. I’m just wondering if we have a base and a rover set up, is it still necessary to have a p4pro with the rtk module or not ?
Hello sir, I am from. Equatorial Guinea 🇬🇶🇬🇶, i really enjoy and learn from your videos, please I have a serious challenge, I have been given a job to work In an area where there are not known points, no survey pillars since the area is basically in the forest, and I want to know how I can create a pillar for future use in that particular area, thank you.
Hello, thanks for the video. Can you talk about the different GNSS equipments. There are some equipment with include a inclinometer for messaging corners of houses. Some of them can messaging above trees, electric lines, etc. Can you explain how good are it and your opinion. I would like to buy a equipment but I don't know with one. I do boundaries, mortgage surveys, topo surveys and stake out, using total station, but I need something faster for working. Thanks. You do very good videos.
I have the previous version the Reach RS plus and the only time I ever got a fixed solution. Doesn’t matter how sunny it can be. Also one of the units is faulty because it disconnects from the Bluetooth
Hi Jonathan, Besides weather, different factors might affect receiving a FIX solution-for example, environmental conditions, baseline, workflow, setup, etc. If you have any issues with getting FIX or Bluetooth connection, feel free to contact us at support@emlid.com. We’ll try to help you.
Wow Sir its nice video i salute you sir for job well done it is very informative a new technique. we you equipment in project sir slope protection as of I am company using total station in as stake survey road works and slope protection in the philippones
Hi Rami, I have two RS-2 (base and rover). My question is which is optimal connection between the base and rover. With my Base connection via MiFi (stationary) would you suggest the rover to use a sim card, LoRan or ??. I'm new to all of this and have sunk a few $$ in the equipment and want to get the best out of my investment.
@Hey Rami. I notice your using the Emlid GNSS receivers. I wanted to know what do you think of them compared to older brands like Topcon, Trimble and Leica. Is the Emlid better or why would the other brands be better or not?
Hi Rami, is the radio connection between the base and the rover can through a dense vegetation or a building. I’ve noticed that he rover lost the fix green each time there is something in between the two recievers.
Awesome video! About to purchase the emlid reach RS2 system base and rover. Going to use it to position grades and elevations (cut /fill) of houses for excavation sites. ( I own a excavation company). Just wondering if you know if you can offset points, radius curves, and slope staking with reachview 3; or if I would have to get a data collection software like FieldGenius? Would I need Microsurvey software too? Would be interesting to know how far down the rabbit hole I need to go. Also, it would be nice to upload the civil engineers plans onto a project so I can survey the site.
We are looking to do the same thing. I just pulled the trigger on 2 RS2 units and FieldGenius today. Hope your process is going well. We do sitework and road striping in Hawaii.
@@kulagabe hows FG going for you? I sent it and bought a Carlson tablet, so running there software because it was recommended to my by the local surveyors.
@@zacbaxter We just set it up today and plan to go and shoot some points we will be excavating for a large retaining wall. It should be a good test to see if we can easy find know points once we have some for reference.
what if i don't know the base coordinates? I use the average single to determine the base coordinates when i don't have it, but when i change the base position and observe the same point i already took with the base in that first position it doesn't match. Help me Rami please

Great video! You did an excellent job both explaining and demonstrating RTK.
Thank you man. It really helped me. I hope you have good time.
Great video Rami. You may need to explain a little more where you get the ellipsoidal height for your base.
Of course there is more to say, so much to say in the world of geodesy. Thanks for you support!

Emlid Flow
Is RTK GPS/GNSS requires additional post-processing?
No it does not! RTK stands for Real Time Kinematic, meaning you get the solution in Real Time.
You will if you want to use actual useful coordinates not wgs84, should have used a local project grid for pickup
My rtk points I took on site shifted. I have known coordinates and have done everything possible but the issue still persist.
Dear if we dont have the coordinate of control point , whats can we do .
