卫星编队飞行的地球扁率摄动分析

Analysis of the Earth oblateness perturbation on formation flying satellites

本文研究了地球扁率 J2 项摄动对卫星编队飞行的影响。首先 ,给出了编队飞行的数学描述 ,推导了轨道根数和相对运动状态的关系式 ;然后 ,将卫星编队的受摄影响分解为整体摄动和相对摄动 ,分别得到了解析解 ,重点分析了相对摄动规律。研究结果对卫星编队的设计有一定的参考价值。

The J 2 effect on satellite formation flying is investigated.First,formation flying is described mathematically,and the relationship between orbital elements and relative motion parameters is derived.Then,the effect on the formation is divided into bulk perturbation and relative perturbation,and both the analytical solutions are obtained with the latter analyzed in detail.This study is of high value for satellite formation design.
