摘要
结合两行轨道根数(TLE)星历与SDP4模型预报BDS IGSO、GEO与MEO卫星30 d轨道,并采用GFZ事后精密星历评估轨道预报误差。将所得轨道预报误差与广播星历、历书的轨道预报误差进行对比,结果表明,本文方法轨道预报精度显著优于广播星历与历书。
Using two-line element(TLE)ephemeris combined with SDP4 model,we predict the 30-day orbits of BDS IGSO,GEO and MEO satellites.We evaluate the orbit prediction errors using GFZ precise ephemeris.Then,we compare the orbit prediction errors of this method with the orbit prediction errors of broadcast ephemeris and almanac.The results show that the orbit prediction accuracy of our method is significantly better than that of broadcast ephemeris and almanac.
