DETERMINATION OF ORTHOMETRIC HEIGHTS USING DGPS

This research included two major components: (1) Evaluate the precision of GEOID96 over Florida and investigate possible places for improvement; and (2) Develop and test simplified guidelines for the observation of ellipsoid heights using the Global Positioning System (GPS). The evaluation of the existing, and generation of an improved, geoid model required access to specialized computer programs and gravity anomaly data. This report reviews the work performed to improve the gravimetric geoid model and the development and testing of guidelines for the use of GPS to obtain ellipsoid heights of adequate accuracy to be combined with the geoid model to derive orthometric heights accurate to 2 to 5 cm.
