摘要
基于2012年年积日为88～95d的60个IGS站的观测数据，利用滑动数据窗口内短弧法方程综合的方法解算导航星座快速精密轨道，然后与IGS精密轨道做比较。结果表明，利用全球分布的60个IGS站的观测数据解算导航星座快速精密轨道，其径向、切向、法向的轨道精度RMS的均值为4．3、6．3、2．4cm，平均为4．3cm。
Based on the observations of 60 IGS stations from 88-day to 95-day in 2012, Rapid precise orbits of navigation constellation are determined by sliding the observation spans and combination of multi short arcs＇ normal equation. Then the orbits were compared with IGS precise ephemeris. The results show that based on the observations of 60 IGS stations, the accuracy of Rapid precise orbits of navi gation constellation could achieve 4. 3cm; the radial accuracy, tangential accuracy and normal accuracy of Rapid precise orbits of navigation constellation respectively achieve 4.3cm, 6.3cm and 2.4cm.
