Research and Application of GNSS Control Network Closed Loop Automatic Search Algorithm Based on Delaunay Triangulation

计算GNSS控制网的同步环和异步环的闭合差是衡量GNSS控制网测量精度的重要依据,然而某些商业GNSS软件不能完全搜索所有闭合环。在建立Delaunay三角网基础上,提出了一种新的GNSS控制网闭合环自动搜索算法,并根据此算法采用C#语言编写软件。结果表明,该算法实现了GNSS控制网所有闭合环的闭合差快速计算和检核,提高了GNSS控制网测量精度,丰富了农业生产实践作业效率。

Calculating loop closure difference of synchronous and asynchronous of GNSS control network is an important basis for measunng the accuracy of GNSS control network,however,some commercial GNSS software cant search all closed ring.A new kind of GNSS control network closed loop automatic search algorithm was put forward on the basis of establishing Delaunay triangulation nct,and c # was used to develop software according to the algorithm.Studies showed that the algorithm realized fast calculation and check of closed error of all closed loop of GNSS control network,improved the measurement accuracy GNSS control network and enriched the practical efficiency of agricultural production.
