摘要
本文论述了按地面同坐标和协方差参考系中的位置基准和方位基准作ＧＰＳ网平差和转换的各种方法，在采用ＧＰＳ定位技术检测和改善原有城市或工程控制网时，宜根据不同情况而选择采用。
This paper deals with all kinds of methods with which the GPS network can be transformed into Gauss'plane according to the location and direction datum in coordinate and covariance reference system of terrestrial network. Based on various situations these methods should be selected, when the urban and engineering control networks are tested or improved with GPS technique.
