Summary

As a result of inadequate data, gravitational models derived from either terrestrial or satellite data alone do not satisfy present and anticipated needs. Since low-degree geopotential coefficients are better determined from satellite data, whereas higher-degree coefficients are better determined from terrestrial data, the best approach appears to be the combination of terrestrial and satellite data to take advantage of the best properties of each. Methods of Rapp, Kaula, Kohnlein, Ballew, Mancini, and Bjerhammar are described and tested. This analysis points to Mancini's method as the best.
