铁岭县GPS控制网高程拟合精度分析

Height Interpolation Accuracy Analysis of Tieling GPS Control Network

利用GPS技术测量点的平面位置可获得较高精度,但不能直接得到地面点的正常高,只能得到大地高。作者探讨了GPS高程拟合的精度与起算点的分布、整体拟合和分区拟合方法的选择、GPS高程拟合精度的分析等方法并提出了自己的见解,且通过铁岭县C级GPS网的高程拟合实例,介绍了该方法的具体应用。

Measurement points using GPS technology can obtain higher accuracy flat position, but can not directly get the normalheight, only get ellipsoidal height. To investigate the accuracy of GPS Elevation Fitting the distribution with the known point, the over-all fitting and partition fitting method of choice, GPS elevation fitting accuracy analysis methods such as put forward their own views,and through C - class GPS Network of Tieling elevation fitting example, the above method is introduced specific application.
