GPS网平差应注意的几个问题

本文介绍了用GPS相对定位技术建立测量控制网的过程，包括GPS控制网的设计、野外观测、GPS基线向量网的计算和GPS基线向量网的质量检验等。重点讨论了GPS网的优化设计、GPS基线向量网的计算和质量检验中应注意的几个问题。

Several questions need to pay attention to on balancing to GPS net

The paper introduced setting up control net using GPS relative positioning technique,including the design of GPS control net,its field observation,the calculation of GPS base-line vector net and the quality check of GPS base-line vector net etc.We focus our discussion on several questions that need to pay attention to in following topics:the optimized design of GPS net,the calculation of and the quality check of GPS base-line vector net.
