Geoid Models

Geoid velocity added to GPS·H

To correct for the vertical drift between reference frames, GPS·H now calculates the velocity of the geoid height (VN), which is incorporated into the calculation of the orthometric height. The header of the geoid model BYN grid format has been updated to support this. View the GPS-H update documentation to learn more. BYN format geoid models with updated headers are now available for download.
