摘要
文章针对GPS城市控制网中通过对GPS高程起算点选取的不同方案的计算结果的统计分析,阐述高程控制点点位的选择,对GPS高程拟合精度提高有很大影响,以及在一定条件下GPS测高方法是可以达到四等水准精度的。
In view of result statisic analysis of different schemes which are obtained throgh choosing origin points of GPS height. It is elaborated that the choice of the network point have great infuce on the precison of GPS height, and that in some condition. GPS height can reach the leveing precison of order 4.
