GPS网建立地方独立坐标系的方法研究

Research on methods for establishment of regional independent coordinate system in GPS network

通过实例,介绍了由平差坐标经高斯投影变换建立地方独立坐标的方法,并分析说明建立的独立坐标系网中各边长尺度的精度,从而完全满足在小区域布设工程控制网建设的需要。

According to the examples,the paper introduces the methods to establish the regional independent coordinate by adjustment coordinate and the guass projection＇s transmission,analyzes and indicates the accuracy for the sizes of all sides＇ length in the establishment of the independent coordinate network,so as to meet the demand for laying engineering controlling network construction in small areas.
