GNSS Positioning by CORS and EGM2008 in Jilin Province, China.The Continuously Operating Reference Station (CORS) technique has been widely applied in land resource management, surveying, mapping, deformation monitoring, precise navigation, etc.  This article analyzed the positioning method using EGM2008 and CORS of Jilin Province, China.  The method proposed in this article expanded the positioning result and its application for JLCORS and other CORS with local datum.

GNSS Positioning by CORS and EGM2008 in Jilin Province, China.The Continuously Operating Reference Station (CORS) technique has been widely applied in land resource management, surveying, mapping, deformation monitoring, precise navigation, etc.  This article analyzed the positioning method using EGM2008 and CORS of Jilin Province, China.  The vertical transformation of EGM2008 from WGS84 to China's CGCS2000 datum and the horizontal coordinate transformation from CGCS2000 to a triangulation coordinate system were discussed.  The results indicated that a local geoid with respect to CGCS2000 can be transferred from EGM2008 with the same accuracy, and the geoid correction between CGCS2000 and WGS84 varied from 0.023 m to 0.111 m.
