摘　　要：我国正在组建的北斗卫星导航系统采用了一定数量的GEO和IGSO卫星,为了验证对MEO(如GPS)卫星适用的轨道数值积分方法对GEO和IGSO卫星是否同样适用,本文在二体意义下分别对GEO和IGSO卫星进行了轨道数值积分,先使用变步长的RKF7(8)阶积分法积分10步后,再使用定步长的10阶Adams预测-校正系统进行积分48小时,然后与其理论值进行了分析比较,结果表明原来适用于MEO卫星的轨道积分方法仍然适用于GEO/IGSO卫星。Compass satellite navigation system is being set up in China with a certain number of GEO and IGSO satellites.In order to verify whether the numerical integration method for MEO (GPS) satellites ok suitable for the GEO and the IGSO satellites,we made numerical orbit integration of GEO and IGSO satellites at the significance of two-body in this paper.This paper first used the step variable numerical integration method of RKF7 (8) to integrate ten steps and then integrate for 48 hours using the step fixed numerical integration method of Adams predictor-corrector.After compared to its theoretical value,we draw conclusions that the numerical integration method for MEO (GPS) satellites is also suitable for GEO and IGSO satellites.
