GPS卫星实时精密定轨及初步结果分析

GPS Real Time Orbit Determination and Initial Results Analysis

  • 摘要: 提出了导航卫星实时精密定轨的滑动窗口短弧法方程综合方法。通过对全球70个IGS站的观测数据进行仿实时解算的结果表明,与IGS事后精密轨道相比,实时轨道精度达5 cm左右,达到IGS事后快速轨道精度的水平。

     

    Abstract: On the basis of sliding the observation spans and combination of multi short arcs' normal equation,a new method of precise real-time GPS satellite constellation orbit determination is proposed.Based on the new method,about 70 IGS stations are used to estimate GPS real-time orbit product.The results show that the accuracy of real-time orbit is about 5 cm,equal to the accuracy level of IGS rapid precise orbit products.
