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。 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.
