%X 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 ...
