It is trend to using Geocentric Geodetic Coordinates in the field of international survey,and GPS station of Continuous Operation Reference System is the most universally method to build the frame of Geocentric Geodetic Coordinates.By using GAMIT GPS observation reduction software and the fiducially positioning method,the tracking data recorder by NANN GPS station of Nanning Continuous Operation Reference System(NNCORS) are processed.It is shown that the quality of the observation is high and the geocentric geodetic coordinates of NANN in ITRF2000 are obtained with a millimeter precision.
