Corrections through internet with no cell signal-Starlink??

[Monte King]

I have not used this equipment since 2016 when it was the original LS/T2 combo. I was stuck with the big "no name here" equipment since 2016. Getting back into it recently. Great stuff and I am very impressed with many of the new features.

One of the big ones being cellular corrections from a "roll your own" RTN. I can see the major benefit of internet vs UHF considering the amount of data being transmitted. However, many places we end up working have no cell signal. Not a big deal yet but I am guessing as time goes more data will be transmitted causing UHF to be inefficient. I personally would love to see NTRIP corrections through satellites. JSTAR is a great concept that would work well for establishing a base real time then switching to UHF for the survey data collection. It would not work well for measuring considering the time to initialize. However, as stated at some point I am guessing UHF will be inefficient due to the amount of data, so even an on-site UHF base will be limited.

The first thing I thought of was Starlink. I looked around and they have something called SWARM for IoT applications. The 3rd question down in FAQ for swarm at link seems to answer my question. If affordable it would be the way to go. Sounds like seamless 4G cell coverage anywhere in the world...Hopefully be sooner rather than later.

Exciting times when you can actually consider RTK anywhere with NTRIP from VRS/RTN network or your own on-site base station.

I've had to use UHF over the past few weeks because a new user is borrowing my T3 base. I always use internal cell with a very small chance I have to use the 1 watt internal. So I picked up the T1M and headed to work. UHF sucks!!! I cannot wait until the day I get my T3 back. I hate it so much that I found my old jetpack that had a bad battery and got it working again. Anything to get off of UHF.

Phillip,
Do you have a SIM card in your T3 or use a hotspot? We use TCP a good bit also but have the hardest time getting the T3 to stay connected to the hotspot. Its just really inconsistent. Some days are no problem and other days I have given up and ran UHF. I have wondered if running a sim in the T3 would fix our issues.

History: Ran 2-T1 with hotspots and Carlson. Upgraded to LS with hotspot and had the same problems you have. Upgraded the boards in the T1 for multi constellation (as close as you could get at the time to a T1M). Then paid the 1k for internal cell and the connection problems went away. Upgraded later to the LS+ and T3 internal cell and hardly ever have problems. Hotspots are hotspots. Gonna have some issues. Not that I wouldn't use them I just prefer internal if it's available. The T1M that I spoke about is a loaner. Problem with the T1 platform (which really isn't a problem) is you have to use a hotspot if you want to run UHF and cell at the same time like the T3 can do. The positive with the T1 platforms. They are built like tanks! I still have my old T1's and they work. I am actually demoing the T1M+ receiver and the T3NR and I am very impressed. I love the little T3NR and I think the 2 watt will help the T1M+ for those that have to rely on UHF without much setup time with an external radio. Personally I think Javad has under valued the T3NR. Print out the specs T3NR/T1M+ and place them beside any receiver any flavor and do a side by side comparison. These new ones are awesome!
