摘要
通过实际采集的北斗广播星历数据分析了GEO广播星历的相关轨道根数特性,介绍了北斗GEO卫星广播星历拟合的坐标旋转法,给出了适用于北斗GEO卫星的轨道计算方法,通过理论分析和试验验证了北斗GEO法的可用性与正确性。
Aimed at solving current BeiDou users＇ biggest block-GEO satellite orbit calculation,we analyze the characteristic of relevant parameters of GEO broadcast ephemeris through the actually collected BeiDou data.BeiDou GEO satellite broadcast ephemeris fitting algorithm adopts coordinate transformation method.And we put forward the GEO satellite orbit algorithm.Through the theoretical analysis and test,the feasibility of BeiDou GEO satellite orbit algorithm is validated.
