| 摘 要： | 本文针对GEO、IGSO、MEO三类卫星,分析了在地球非球形引力影响下的卫星轨道根数变化情况。并采用两年的精密星历反算了GPS卫星的轨道根数长期变化情况,分析了其周年、半年、半月变化的产生原因。对卫星入轨偏差影响进行了分析,得出轨道长半轴入轨偏差是决定卫星实际轨道相对设计轨道演化的重要因素。最后对星座相对结构演化及轨道西移的影响进行了分析。

| Abstract: | The changes of satellite orbital elements influenced by earth potential perturbation are analyzed with respect to three kinds of satellite(GEO,IGSO,MEO).The long term changes of satellite orbital elements are computed inversely through precise ephemeris of two years.The reasons of its annual,half-annual,mensal changes are analyzed.The effects of the bias of injecting orbit are researched.The bias of injecting orbit is the important factor deciding the evolvement of actual satellite orbits compared with the designed satellite orbits.At last the evolvement of constellation configuration and orbit westward motion influences are researched. |
