| 摘 要： | 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。

| Abstract: | 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. |
