研究了利用电推进系统进行 GEO 卫星轨道保持问题，给出了一种基于日预报的位置保持策略。首先，根据 GEO 卫星轨道漂移规律，分析了小推力推进系统每日进行位保的可行性；然后，针对四电推力器配置构型，给出了每日轨道误差、各推力器工作时间与区间的预测方法；进一步，针对给定的定点位置，根据位保效果对电推进安装角进行了优化选择，并研究了推力变化对位保效果和燃料消耗的影响。以东经100°定点为例对所给方法进行了仿真验证，数值结果表明：所给策略可有效用于 GEO 卫星位置保持。

Problem of station keeping of GEO satellite using electric propulsion is analyzed,and a station keeping method based on daily prediction was proposed.On the basic of GEO satellite drift characters,feasibility of daily station keeping using low thrust was discussed.Furthermore,a method of predicting daily orbit error,thruster working time and phase was proposed specific to four thrusters configuration.Then it optimizes gimbaled angles subject to performance of station keeping at a geostationary position.The influence on control effects and fuel consumption with thrust changing is summarized.The method is evaluated by simulating at 100°E,which indicates that it can be used for GEO satellite station keeping.
