摘要:

为满足我国卫星导航系统状态切换中地影时间确定以及卫星轨道确定中太阳辐射压建模等需求,本文针对GEO、IGSO、MEO三类导航卫星,采用柱形与锥形地影模型进行了地影因子及本影区持续时间差异分析。在此基础上以地影期持续天数,本影区持续时间为分析对象,对卫星轨道根数与地影状态之间的关系进行了深入研究。

关键词: GEO, IGSO, MEO, 锥形地影模型, 柱形地影模型

Abstract:

To meet the need of earth eclipse time determination in satellite navigation system’s state switching and solar radiation pressure modeling with orbit determination, this paper analysed the difference of cylindrical and conical model in eclipse factor and umbra duration calculation for GEO, IGSO, MEO three types of navigation satellites. And then the number of days suffering earth eclipse in a years’ time and the umbra duration in one day are analysed in order to obtain the relationship between orbit elements and earth eclipse status.

Key words: Geostationary Earth Orbit, Inclined Geo-Synchronous Orbit, Medium Earth Orbit, Conical shadow model, Cylindrical shadow model
