| 摘 要： | 计算GPS网中的同步环或异步环闭合差是检核GPS控制网测量精度的重要依据,手工方式费时又容易出错,而某些商业软件搜索闭合环存在一定的缺陷,无法搜索到所有的独立闭合环.为此,在构建Delaunay三角网的基础上,提出了一种新的GPS控制网同步环和异步环自动搜索算法.实验证明,该算法实现了GPS网中所有可能的同步环、异步环...

| Abstract: | Calculation for closing errors of simultaneous or asynchronous rings in GPS network is an important basis for checking the measurement accuracy.Searching for closed rings in the manual mode or with various commercial softwares has some flaws,can not find all of the independent closed rings.So,a new automatically searching algorithm for simultaneous or asynchronous rings based on Delauney triangulation is presented.The experiments show that the new algorithm can be used for calculating and checking rapidly a... |
