Abstract

The spaceborne gravity field mission concepts SST (satellite-to-satellite tracking) and SGG (satellite gravity gradiometry) are considered to have the potential to improve our knowledge of the Earth’s gravity field with respect to accuracy and resolution by one order of magnitude or even more. In this paper the twenty five years history of the various activities to realize a satellite gravity field mission is briefly reviewed. Mission scenarios currently discussed are sketched and compared from a unified point of view. Error simulations are presented showing the benefit of these mission concepts for the improvement of the accuracy of the potential coefficients of Earth.
