An Improved Energy Balance Approach and Its Application in CHAMP Gravity Field Recovery被引量：1
《Geo-Spatial Information Science》2008年第3期168-173,共6页XU Tianhe HE Kaifei 
Supported by the National Natural Science Foundation of China （No.40604003, 40474001）. Acknowledgements： We are grateful to the ISDC of the GFZ Potsdam for providing the data and to Gerlach C. and Svehla D. at the TUM for the kinematic orbits.
An efficient method for gravity field determination from CHAMP orbits and accelerometer data is referred to as the energy balance approach. A new CHAMP gravity field recovery strategy based on the improved energy bala...
