No RTK solution obtained
Cause	Solution
The satellite geometry is unsatisfactory (the PDOP values are too high).	Do the survey where satellite visibility is better (low PDOP value). Make sure that the elevation mask is less than 10 degrees. Increase the PDOP threshold: Select Receiver SettingsTrackingObs on the TRU main screen.
Incorrect base station coordinates are configured.	Enter the correct base station coordinates on the web UI, TRU, or with different applicable field data collection software.
The base station does not operate.	Make sure that the power to the base station is set to On and that it has sufficient power.
The base station and rover have different radio parameters.	Make sure that the radio parameters are the same for the base station and rover: Channel / Frequency Modulation Protocol Link Rate
Radio communications have interference.	Change the RF channel (if possible). Remove the source of the jammed signal or move the radio antennas (if possible).
There is a discrepancy between the differential corrections used by the base station and rover.	Make sure that the base station and rover receivers use the same GNSS corrections output/input format.
The radio antenna is incorrect.	Make sure that the radio antennas installed on the base station and rover receivers are correct for the radio and frequency band used for RTK correction. See the Main components topic.
The distance between the base station and rover is too far.	Decrease the distance between the base station and the rover. Use repeaters to increase radio coverage.
