摘要
研究如何根据GPS原理和作业特点制定GPS的布网方案,对减少外业观测劳动强度、提高观测质量和精度等具有重大的意义。本文通过对布设的GPS控制网的观测,对获取的野外数据进行随机软件平差计算,对GPS控制网点连式、边连式、边点混连式控制网进行技术、经济、可靠性分析对比,提出合理的GPS控制网布设方案。
Researching how to draw up the fibaric net scheme of GPS on the basis of GPS＇s rule and task distinguishing features,to decrease outward viewing labour intensity,lift viewing quality and accuracy have great significance.Based on viewing to grounds GPS＇s control net,do random software adjustment calculation to the field data,to compare the technology of the GPS＇s control network style point style,edge style,edge point mixed style,propose reasonable scheme of GPS＇s control net.
