’92中国GPS会战（A级网）数据处理分析

Data Analysis of' 92 GPS Campaign in China

讨论了应用武汉测绘科技大学改进到微机上的ＧＡＭＩＴ软件处理’９２中国ＧＰＳ会战的国内数据以及用ＧＰＳＡＤＪ软件的多站网处理模块进行全网平差的技术方案，着重论述了数据处理所遇到的问题及解决方法，最后分析了成果精度。

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 X10-8,and the repeatability of the vertical component is better than 9 X 10-8. The ralative accuracy of baseline length after network adjustment is about 3 X 10-8 and the accuracy of station position is about 6cm.
