| Abstract: | The accuracies of the EGM2008 and EGM96 are compared by using the 854 GPS/leveling observations in China area.The results show that there is the evident systematic error between the geoids heights derived from the models and those from the observations.When the systematic errors are removed,the accuracies of EGM2008 and EGM96 are all improved.The 289 GPS/leveling observations in the western China are calculated,it is indicated that the EGM2008 is better than EGM96 in the western China. |
