Computation of a new Earth’s gravity field model is difficult or even impossible if without a priori information about the gravity field. It is important to understand how incorporation of this information at different stages of gravity field modeling could influence the final results. The focus of the paper is on a technique based on satellite accelerations; a version of this technique was used earlier...
Performance of a recently proposed technique for gravity field modeling has been assessed with data from the CHAMP satellite. The modeling technique is a variant of the acceleration approach. It makes use of the satellite accelerations that are derived from the kinematic orbit with the 3-point numerical differentiation scheme. A 322-day data set with 30-s sampling has been used. Based on this, a new...
