摘要
绕地卫星摄动运动是导致星座设计构型发散的主要因素,摄动补偿轨道控制是维持全球星座构型的基本策略。本文利用摄动分析法,通过建立星座轨道相对摄动运动方程,给出全球星轨道摄动规律和星座轨道整体飘移相对摄动运动规律,通过建立星座轨道摄动补偿控制绝对和相对运动控制方程,比较了星座轨道绝对控制和相对控制策略的控制量需求,并探讨了两者的优缺点,为设计全球星座轨道和制定运控策略提供参考依据。
In view of the regression properties of Compass-M navigation constellation caused by the perturbation forces implied to the satellite,the perturbation compensation based orbit maneuver strategy should be deployed to maintain the constellation configuration. This paper details the perturbation motions caused by the Earth＇s none spherical gravity,the Solar and Lunar as well as the radiation force for global navigation satellite,and presents the relative motion equations with each other and with the rotation of the Earth to measure the regression of constellation configuration,also,two anti-perturbation orbital maneuver strategies are discussed in order to maintain the configuration with inertial space or relative to the rotation of the Earth respectively,and the real flight orbital data has taken to assess the conclusions achieved in this paper.
