Waypoint® Post-Processing Software

GNSS post-processing offers many advantages over real-time operation. Precise real-time GNSS using RTK requires a robust data link for GNSS corrections data. If a real-time solution is not required, the raw GNSS measurement data can be collected in the field and processed post-mission to provide a precise position and velocity solution. Post-processing allows for simplified real-time system operation without the need for real-time telemetry and allows lower-cost receiver hardware to be used.

GNSS/INS post-processing allows for greatly reduced solution drift when operating with limited GNSS availability. Combining and smoothing the trajectories computed forwards and backwards in time results in an improvement in the position, velocity and accuracy available over what is available in real-time.
