网络RTK技术在城市线路测量中的应用研究

简要介绍了网络RTK技术的原理,总结了其在作业过程中的几点优越性,结合长株潭GNSS连续运行参考站系统（CZTCORS）探讨了网络RTK技术在城市线路测量中的应用,将RTK纵横断面测量结果与全站仪纵横断面测量结果进行了对比,分析表明中桩测设的精度明显优于传统测量方法,RTK的横断面测量也能达到较高的准确性,验证了网络RTK技术应用于线路测量具有巨大优越性。

The Application Research on Network RTK Technology in Urban Route Survey

In this paper,the principles of Network RTK technology is briefly introduced and its advantages are summarized.The application of Network RTK in urban route survey combined with the CZTCORS is inquired.And the Vertical and Cross Section Survey results measured by Network RTK are compared with the results measured by Electronic Total Station.The comparison remarks that the Vertical Section Survey results measured by Network RTK are better than the results measured by traditional method.And the Cross Section Survey results also can achieve higher precision.The analysis demonstrates that the Network RTK has great advantages in urban route survey.
