Abstract : The accuracy with which the Earth's gravitational field can be defined from an analysis of satellite data is strongly dependent upon the satellite constellation used. The constellation selected must satisfy several criteria. The objective of this study was to produce quantitative information on the effects of the geopotential harmonics on the motion of satellites for a large variety of orbits. These data can then be used to investigate satellite constellations that will yield useful geodetic information. (Author)
