GNSS Post-Processing Software

Waypoint SoftwareFor applications requiring highly accurate post-mission position, velocity or attitude, post-processing is an ideal solution.

Post-processing maximizes the accuracy of the solution by processing previously stored Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU) data forward and reverse in time, and combining the results. The position, velocity and attitude solution can be smoothed and output at the required data rate and in the coordinate frame required. This process also provides the ability to assess the solution reliability and accuracy.
