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

ZHAO Qile~1 LIU Jingnan~(1) GE Maorong~(1,2) SHI Chuang~(1,2)(1 Research Center of GPS,Wuhan University,129 Luoyu Road,Wuhan 430079,China) (2 GFZ Potsdam,Telegrafenberg A17,Potsdam 14473,Germany)  
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.
