Abstract: The strategies for the data pocessing of the '92 GPS campaign in China using GAMIT(GPS analysis software) and GPSADJ(GPS network adjustment software) on a Personal computer is discussed first.Then some problems in the data processing and the corresponding solving methods are described in detail.At last the results of the data processing is analysed.The repeatability of horizontal components and baseline length is better than 5×10^-8,and the repeatability of the vertical component is better than 9×10^-8.The ralative accuracy of baseline length after network adjustment is about 3×10^-8 and the accuracy of station position is about 6cm.
