description In order to improve the accuracy of GPS leveling fitting, a method of leveling fitting based on the EGM2008 gravity field is proposed, which uses the "remove-restore" method. By fitting experiments, the results show that the precision of the "remove-restore" method based on gravity field model is higher than that of the conventional fitting method, and can reach 1 cm.
