Practical Considerations in the Use of FFT Methods for Computing Terrain Effectserg (1990). This interest is well justified by the computational efficiency of the methods, and procedures which were once theoretical curiosities can now be used on an every-day basis. Two other factors are contributing to the accuracy and importance of the methods. These are the availability of hi

Estimation of the Disturbing Potential Components and Comparison with GPS and Astrogeodetic Datan test area. Experiments using gravity data and different truncations of the geopotential expansion are carried out in order to obtain for absolute geoidal heights an accuracy close to 0.40m and for relative geoidal heights 2–3 ppm. These results have been derived by comparing the computed gravimetr

OSU89A/B Potential Coefficient Modelst fits (carried out by NASA) showed improvement over GEM-T2. After correction for sea surface topography, orbit error and permanent tidal effects, the geoid undulations from the OSU89B model have an RMS discrepancy with the Geosat implied undulation of ± 59 cm over a complete 17 day repeat cycle.
