Abstract The China Geodetic Coordinate System 2000 is a new generation of the national geodetic coordinate system. Having explained briefly the background and the basic principles of setting up the new generation national geodetic coordinate system, this paper expounds its definition and realization, gives the defining constants and derived constants of the reference ellipsoid used and the related formulas for the normal gravity, and finally addresses several items noting on the coordinate system.
Key words ：
China Geodetic Coordinate System 2000
geocentric geodetic coordinate system
reference ellipsoid
normal gravity formulas
constant
