I bought a Trimble 5800 GPS receiver and i want to test it with Carlson SurvCE 2.58. I set the 5800 as a NTRIP Rover: Bluetooth connection with 5800, RTK correction trough data collector or direct to port 2 of the 5800.
And now the strange behavior: when i select a base under 5 km everything is OK, I obtain fixed solution. When I choose a base at a distance greater than 5 km, I can't obtain fixed solution, only DGPS solution and the number of satellite used to calculate position fluctuate.
Please help me with some information.
