| Abstract: | This paper introduces CORS system and EGM2008 global gravity model. And it sets high grade control points in the river reach of Chongqing main city area, makes 3D coordi-nate conversion and test of CORS based on EGM2008 global gravity model. It confirms the high precision and reliable of 3D coordinates based on CORS EGM2008 global gravity mo-del, real y realizes the GPS real time three dimensional meas-urement with high precision, which has a certain reference va-lue. |
