中文摘要：

通过模拟轨道，利用动力法对星载加速度计校准进行了研究。用不同参考重力场模型获得的校准参数分别重新积分卫星轨道，与模拟轨道的差异最大可达m级。结果表明，参考重力场模型误差对加速度计校准的影响不可忽略，在校准加速度计的同时应解算重力场模型，以削弱模型误差的影响。

英文摘要：

The calibration of onboard accelerometer using dynamic method and the simulated orbit is studied in detail. Based on the calibration results from different reference gravity model, integrating the satellite orbit again and compared to the simulated orbit respectively, the maximum difference is on the order of meter, which shows that the impacts of the reference gravity model on the calibration of accelerometer cannot be negligible. The further in- vestigation demonstrates that a better strategy is to calibrate the accelerometer and estimate gravity model parameters simultaneously to remove the aliasing error of the reference gravity model.
