| Abstract: | To improve the GPS leveling fitting accuracy of complex terrain,the authors analyzed the accuracy and application state of EGM2008.Through taking two test areas in Northwest China as examples,the accuracies of height fitting were studied with the method of removing-restoring Earth gravity field combined with conventional GPS leveling fitting and comparison with the result only with conventional method.The results show that the removing-restoring method based on Earth gravity field can achieve better accuracy in complex terrain areas. |
