GNSS signal tracking options

To use observations from a GNSS constellation in a real-time or postprocessed survey, you must enable tracking for each signal type you want to use in both the Rover options and the Base options screens. In a real-time survey the tracked signals are sent in the RTK data stream. In a postprocessed survey the tracked signals are saved in the logged data.

 

  • GNSS signals tracked by the rover receiver must also be tracked by the base receiver.
  • If you enable tracking of satellite signals that are not being tracked by the base or contained in the RTK messages coming from the base, then those signals will not be used in RTK at the rover.
  • To save receiver battery power, enable only those signals available in the base data you are going to use.
  • GNSS surveys with firmware earlier than version 6.00 must contain either GPS or BeiDou observations, and signal tracking for both GNSS constellations is enabled in new survey styles. If you disable one, then tracking the other constellation is automatically enabled.
  • The GNSS signal tracking options are not shown with the Trimble DA2 receiver
