摘要
阐述了GNSS-RTK的工作原理,分析了常规RTK与网络RTK基本工作思想、系统组成及两者的区别,以T8型GNSS接收机与Land Star7. 0测量软件为例,详细介绍了RTK技术进行道路纵横断面测量的方法。依托学校公路勘测实习基地,开展了RTK高程与水准测量高程对比性试验研究,结果表明,两者高程最大差值不超过4cm,RTK高程能满足道路纵横断面设计的精度要求,具有一次完成道路中桩放样与纵横断面测量的优势。
This paper expounds the principle of GNSS-RTK,and analyzes the basic working thoughts,system composition and differences between the conventional RTK and the network RTK. Taking T8 GNSS receiver and LandStar7. 0 measuring software as an example,the method of measuring road criss-cross section by RTK technology is described in detail. By relying on the highway survey and practice base of the school,a comparative test study was carried out on the elevation of RTK and leveling. The results showed that the maximum difference between the two elevations was no more than 4 cm,and the elevation of RTK could meet the accuracy requirements of the design of criss-cross section of road,and it had the advantage of completing the measurement of middle pile lofting and criss-cross section of road in one time.
