基于网络RTK图根控制测量数据后处理及分析

摘要

With the rapid development of the RTK technology in the field of Global Positioning System,many cities have built the RTK system and applied it in engineering surveying filed. However, research on the data accuracy analysis is lacking. Based on the practice and the adjustment of free network,this paper proposed a method that can improve precision of the observation data,which has reference value for the RTK observation data itself.%GPS网络RTK技术在工程应用领域发展比较迅猛,目前国内许多城市已经建立了自己的网络RTK系统,将其大面积应用于工程测量领域,而对其采集的数据精度再分析及改进没有相关的研究,文章将结合工程实践及自由网平差理论提出改进网络RTK图根控制点点组整体精度的方法,通过比较研究得出的结论使观测数据精度进一步提高,对网络RTK观测数据误差研究具有参考价值.
