游动九参数法用于大区域GPS坐标转换的研究与实践

Research and Practice of Moving Nine Parameters used in Large Area GPS Coordinate Transformation

基于大区域GPS成果转换问题,利用Delaunay三角形的基本原理,提出了游动九参数坐标转换法。利用该法对实际GPS控制网坐标成果进行转换,取得了较理想的结果,为大区域的GPS坐标成果转换提供了一种可行的方法。

Based on the GPS transformation in the large area, using the basic principle of Delaunay triangle, it brings up the coordinate transformation method of the moving nine parameters. And using this method to transform the actual GPS controlling network coordinate,it gets the perfection results, and it provides a feasible method for the GPS coordinate transformation in the large area.
