| 摘 要： | 给出了用于标校CHAMP卫星加速度计数据的动力学法,并推导了相应的计算公式。该方法不受先验地球重力场模型的影响,具有在求解位系数的同时对加速度计数据的尺度和偏差进行标校的优点。计算结果表明,该方法能明显改善重力场模型的恢复精度。

| Abstract: | 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. |
