GRAVITY FIELD RECOVERY BY USING ENERGY CONSERVATION APPROACH
基于能量守恒方法恢复地球重力场模型

The energy conservation approach used for simultaneously resolving bias,scale factor,bias drift and potential coefficients based on LEO(low earth orbit)orbit data and non-gravitational accelerometer data is presented.The approach does not require any initial values of unknown parameters and the influence of a prior gravity field model can be avoided.A gravity field model up to degree and order 89 named SWJTU-GRACE01 is recovered from 102 days data of GRACE satellite.The model is compared with international ...
