WGS84 coordinate systems and CGS2000 National coordinate system transformations

The detailed definitions of the two coordinates are omitted from the table, only the problem of their mutual conversion.

In the 84-coordinate era, the difference between its and WGS84 coordinates is still larger. In the cgs2000 era, the reference to the relevant literature shows that the difference between the two is negligible. In view of the comparison between the definition and implementation of the coordinate system, we can assume that CGCS2000 and WGS84 (G1150) are compatible, and that the CGCS2000 and WGS84 (G1150) coordinates are consistent within the implementation accuracy of the coordinate system.

2000 China Geodetic coordinate system and its comparison with WGS84

The definition and realization of 2000 China Geodetic Coordinate system (CGCS2000) and its comparison with WGS84 are expounded. CGCS2000 is the geocentric geodetic coordinate system, which uses the GRS80 ellipsoid, which is realized by the coordinates and speed of the 2000 National GPS Geodetic Network in the calendar element 2000.0. CGCS2000 is consistent with the ITRF, and is compatible with WGS84.
