The calibration method for CHAMP accelerometer data based on the dynamical method is given out,and the corresponding formulae are derives out.This method can com-pute the geopotential coefficients and the scale and bias parameters for calibrating accelerom-eter data at the same time.The results show that this method is feasible and can obviously improve the accuracy of recovered geopotential;therefore the accelerometer calibration is necessary in recovering the geopotential model.
