Abstract:

Geodetic coordinate systems are fundamental to the study of geodesy. We start by defining several coordinate systems, such as a rectangular space coordinate system, a geodetic coordinate system, a topocentric coordinate system and a planar coordinate system. Then the World Geodetic System WGS72 and WGS84 and International Terrestrial Reference Frames ITRF2000 and ITRF2005 are introduced. The history of international geodetic coordinate systems in Antarctica is briefly reviewed and the development of geodetic coordinate systems at the Great Wall Station and Zhongshan Station is introduced. Finally, the issue of coordinate transformation is discussed.
