CHAMP gravity field recovery using the energy conservation method

SONG Lei~(①),WU Bin~(②),PENG Bi-bo~(②), ZHOU Xu-hua~(②)(①The graduate student department of HoHai University,Nanjing 210098;②Key Laboratory of Dynamical Geodesy,Institute of Geodesy and Geophysics,Chinese Academy of Sciences,Wuhan 430077)  
In this paper,the theory and method of gravity field recovery using CHAMP satellite PSO(post-processed science orbit)data and accelerometer data based on the energy conservation method were discussed.After considering the earth rotation and non-conservative forces energy dissipation,the energy conservation equation was presented.The formula of the gravitation potential and tide-generating force additional potential of sun and moon were given in detail. The disposal of accelerometer data was introduced.Based on the energy conservation theory,using 180 days CHAMP satellite PSO and accelerometer data in three different periods of month 1-2,7-8 and 11-12,2002,three global gravity field models of 50 degree that named GFM01,GFM02 and GFM03 were recovered.These gravity field models were compared with models EGM96 and EIGEN-CG01C.The results showed that the series GFM gravity field models recovered by the energy conservation method were well consistent with EGM96 and EIGEN-CG01C gravity field models in low-degree potential coefficients,but they were in a better agreement with EIGEN-CG01C models.All these indicated that CHAMP is sensitive in medium and long wavelength of global gravity field and the energy conservation method is an efficient one for recovery low-degree potential coefficients of global gravity field.
