均方根信息滤波和平滑及其在低轨卫星星载GPS精密定轨中的应用

Applications of Square-Root Information Filtering and Smoothing on Orbit Determination of LEO Satellites with On-Board GPS Data

    摘要
  • 摘要: 从均方根信息滤波和平滑的基本原理出发,结合卫星定轨的实际特征,导出了其在精密定轨软件中实现的详细公式;针对均方根滤波的特点,提出了快速高效地探测和修复GPS观测数据中周跳的新方法。利用实测星载GPS数据验证了基于均方根滤波的质量控制算法的可靠性,得到了有益的结果。

     

    Abstract: The realization of square-root information filtering and smoothing in orbit determination software is discussed,a new real-time quality control method based on SRIF/SRIS is presented.The on-board GPS data of CHAMP satellite is processed by SRIF/SRIS module of PANDA software.The results show that even small slips can be surely detected and the reduced dynamic orbit of CHAMP can reach 5-8 cm,when 24 IGS station were solved simultaneity.
