用GPS静态测量做地质勘探区首级控制的应用解析

Application of GPS static survey in the geological prospecting area

该控制网位于延吉市南部松江镇附近的地质勘探区内,此处山高林密用传统方法进行控制测量比较困难。本文主要是论述了在此等条件下,我们应用GPS静态测量方法布设控制网、进行野外采集数据、应用平差软件平差解算、介绍了解算过程中各边、环及点位的精度情况。实践证明这项技术比传统光电测控制网有诸多优势。

The control network is located in the geological exploration zone near the south Songjiang, Town of Yanji City. Due to the high mountains and thick forests, control survey using traditional methods are difficult. This paper mainly discusses layout control network, application of GPS static survey method adjustment of field data, the application of software adjustment calculating, and decoding process, the precision of each side, the ring and the point. The practice proves that this technology has many advantages than traditional photoelectric measuring control network.
