Earth's gravitational field model determination from different types of gravimetric data based on iteration method

LIU Xiao-gang1,2,3,PANG Zhen-xing1,2,WU Juan1,2 (1.Xi'an Research Institute of Surveying and Mapping,Xi'an 710054,China;2.National Key Laboratory of Geo-Information Engineering,Xi'an 710054,China; 3.Key laboratory of Geospace Environment and Geodesy of Ministry of Education,Wuhan University,Wuhan 430079,China)  
Different types of gravimetric data include Earth's gravitational field information in different wave bands,so these data should be combined together in the data processing in order to recover the Earth's gravitational field model(EGM) in a higher precision.Taking the ground gravity anomaly Δg for example,the fundamental formulae of iteration method used in the recovery of EGM from different types of gravimetric data are deduced with the detailed realization steps given next.Then,the EGM computed by satellite gravity gradient(SGG) data is further refined by global gravity anomaly Δg and disturbing potential T data based on iteration method.The initial EGM computed by SGG data and the iterated EGM refined by global gravity anomaly Δg data are obtained here,of which the cumulative geoid errors are about 1.128 cm and 0.048 cm respectively,while of which the cumulative gravity anomaly errors are about 0.416 mGal and 0.018 mGal.Besides,the cumulative errors of geoid and gravity anomaly of the iterated EGM refined by global disturbing potential T data are about 0.043 cm and 0.016 mGal.
