Effects on Satellite Formation Flying of Tiny Aspherical Gravitation of the Earth

Abstract:

J₂ perturbation has been widely studied for satellite formations in low earth orbit. However, the effects of some tiny aspherical gravitational perturbations such as high-order zonal harmonic perturbations, sectorial and tesseral harmonic perturbations are not negligible for long term formation flight. In this paper, after eliminating the effects of J₂ perturbation which accommodating it, research these tiny perturbations uses numerical analysis and acquires some conclusions. High-order zonal harmonic perturbations may cause divergence in radial, in-track and cross-track direction, while the drift caused by sectorial and tesseral harmonic perturbations is larger than higher-order zonal harmonic perturbations about two magnitudes generally, and drift in cross-track direction is secular.
