I have installed an Ardusimple RTK2b reciever on my rover and would like to use the local NTRIP service for RTK corrections. It seems to login ok and I get to an RTK fix however it doesn’t seem to stay with a fixed solution for very long ie only about 1 minute. Also, on the RTK inject page I get an error message saying “Configuration of fixed position in Septentrio failed.”
When I tried RTK on a rover I have been mostly in RTK float; however, the place had a lot of trees around.
You may check the satellites conditions at the place and time of your test: Trimble GNSS Planning
or try to test choosing in advance the lowest HDOP interval (best below 0.4).
