Abstract Based on GRACE-FO data of January 2019, using the dynamics method with 24 hours arc length, we analyze results of orbital fitting and time-variable gravity field recovery by adopting different accelerometer parameterization strategies. The results show that: the results of orbital fitting are related to the number of parameters in the accelerometer calibration, and the results would be better with the increasing of accelerometer calibrated parameters. Further, there is not the conspicuous improvement in fitting orbit whatever the strategies are used in directions of the three-axis accelerometer. However, the performance of results of the recovered gravity field is influenced by the number of parameters in the accelerometer calibration, and present some differences if we take different strategies at different directions. Through the cases we investigate, the result would be better if we estimate more accelerometer parameters on the Y direction in SRF frame than other cases, especially, at degrees greater than 40.
