I have been asked to layout a house for excavation in a remote area with limited cell reception. Normally, I would go out with a rover receiving corrections via NTRIP and stake my points out and that would be that.
This time, however, I have only one small area on site with cellular data reception access.
My question is this: Can I set up one of my RS3s as a base receiving NTRIP corrections, and then output corrections to my rover using LoRa? How effective is this? I am usually within a cm or two when using rover/NTRIP only.
You can’t directly transmit NTRIP corrections over LoRa in the way you’re describing. What you can do instead is set up your own base station and rover via LoRa. The base station calculates its position and sends correction data to the rover, allowing it to improve its accuracy. This is similar to your NTRIP setup, where an NTRIP base sends corrections to your RS3 rover via the Internet.
As long as you’re getting a FIX solution, the accuracy will still be at the centimeter level. For LoRa, it’s important to have a clear line of sight between the base and the rover, as obstacles can affect the signal.
