Description
Height smoothing is a filter applied to all heights measured in the WGS 1984 or a local coor-
dinate system or output via NMEA. The filter defaults are best suited for high dynamic vari-
ations in height up to 1 m/s as carried out by graders.
Height Smoothing with high dynamic GPS operations
All GPS computed positions are almost twice as accurate in plan than in height. For the posi-
tion determination, satellites can appear in all four quadrants. For the height determination,
satellites can appear in two quadrants. This weakens the height position compared to the
plan position.
