Abstract：Based on the dynamic method，observation error of gravity satellite and its influence on gravity fieldsuch were fully analyzed through simulation experiments.The results show that the contribution of orbital determination precision on gravity field is in loworder，while contribution of intersatellite ranging precision on the gravity field is in middletohigh order.When orbital precision keeps at 2-3 cm level，resolution accuracy of gravity field depends on intersatellite ranging data，that is，the higher precision of intersatellite ranging data is，the higher inverse precision of gravity field is.However，orbital determination precision impacts low order part of gravity field when intersatellite rangingrate reaches nanometer level with invariable orbital error.Therefore，improving orbit determination precision might be one of the key issues in new generation gravity field satellite mission.
