Simulation Research on Precise Orbit Determination for GIOVE-A

    摘要
  • 摘要: 基于GPS系统的实测数据,在极为类似的条件下,仿真研究了GIOVE-A卫星的精密定轨问题。以IGS提供的GPS精密星历为时空基准,利用12个全球分布的跟踪站数据,在精确确定地面站坐标、精密时间同步以及确定对流层参数的基础上,进一步利用单颗GPS卫星仿真GIOVE-A卫星实施了精密轨道确定。结果显示,采用本文方法计算的单颗导航卫星轨道的三维位置精度优于50 cm,径向精度达到了10 cm。

     

    Abstract: Single satellite orbit determination results based on position and navigation data analyst software(PANDA) using the data received by 12 tracking stations are presented.By considering GPS precision orbits as space-time base,the precision coordinates,receivers clock,and ZTD parameters are estimated,and the orbit of one satellite of GPS as simulation satellite is computed.Difference of orbit compared with IGS precision orbit and LC residuals are derived to assess the orbit quality.The results show that the orbits are determined with an accuracy of about 10 cm in radial orbit component,and about 50 cm in 3D position.
