Reducing influence of gravity model error in precise orbit determination of low Earth orbit satellites

  • Published:
Geo-spatial Information Science

Abstract

Based on the orbit integration and orbit fitting method, the influence of the characters of the gravity model, with different precisions, on the movement of low Earth orbit satellites was studied. The way and the effect of absorbing the influence of gravity model error on CHAMP and GRACE satellite orbits, using linear and periodical empirical acceleration models and the so-called “pseudo-stochastic pulses” model, were also analyzed.
