Abstract

The original data from a number of GPS campaigns carried out in the last 10 years are aggregated to construct the National 2000' GPS Geodetic Control Network and the positions of 2482 GPS sites at 2000.0 epoch with respect to the International Terrestrial Reference Frame (ITRF) are obtained. In this paper, we introduce the method for processing GPS data, deriving site velocities from GPS data, establishing the crustal motion velocity field of the Chinese mainland, and carrying out the network integrated adjustment employing a Kalman filter. The accuracy analysis of GPS daily solutions and final coordinate solutions are presented. A series of technical steps have ensured the rationality and reliability of our results.
