起算点的分布和基线连接方式对GPS工程控制网的精度影响分析

摘要

With its advantages of high precision,all-weather and easy to operate,GPS is widely used in the establishment of various engineering control networks.Through several sets of experiments this paper analyses the influence of the different initial data distribution and the different baseline connection to the GPS control network adjustment accuracy,trying to draw some useful conclusions and to provide a certain reference to the practical work.%GPS以其高精度、全天候、外业操作简单等优点,广泛应用于各种工程控制网的建立。本文通过几组相关实验,分析不同起算点分布以及不同独立基线连接方式对GPS控制网平差精度的影响,得出一些有益的结论,对生产实践工作具有一定的借鉴作用。
