| 摘 要： | 地球同步轨道上的GEO卫星接近寿命末期时,星上的有效载荷和电子元器件等仍能正常应用,此时如果只做东西方向的位置保持,可以大幅度延长卫星的在轨工作寿命。简要介绍了引起GEO卫星轨道变化的主要摄动力,利用STK软件分析寿命末期GEO卫星的运动规律,并给出这类GEO卫星轨道演化的仿真分析流程,用以指导寿命末期GEO卫星的开发应用工作。

| Abstract: | When a Geostationary-Orbit(GEO) satellite is close to its end of life,its payload and electronic components can still be used normally.Therefore,if east-west station keeping maneuvers are adopted,the operational lifetime of satellite can be greatly extended.This paper briefly describes main perturbation forces causing the change of a GEO orbit.We apply the STK software to analyze the motion of a GEO satellite near end of life,and give a simulation process for GEO satellite orbit evolution as a guide for exp... |
