| 摘 要： | 连续运行参考系统(CORS)的核心技术——GPS网络实时动态定位(RTK)技术已经成为GPS高精度定位中一种重要技术,其定位精度与站间距离密切相关。在构建了站间距离和网络分布适中的Delaunay三角网后,探讨了基准站点删除与插入等网络局部更新以及参考站最优选择问题,提出了构网和确定流动站所在三角形的优化算法,实验证明该算法高效快捷、简便可靠。

| Abstract: | As a core technique of CORS,GPS network RTK has been developed as one of the most important techniques of precise GPS positioning.The positioning precision depends on the distance between fidueial stations and the distribution of the CORS fiducial station networks.This paper discusses partial updating are put forward,which have been proved fast,efficient,simple and reliable. |
