GPS连续运行服务系统在铁路勘测定界中的应用

Application of GPS Continuous Operation Service System in Railway Survey and Demarcation

CORS技术集计算机网络管理技术、Internet技术、无线通信技术和GPS技术于一体,采用了最先进的多基站网络RTK算法,代表了继常规RTK技术之后的新一代定位技术发展方向。文章以西安铁路局勘测定界项目为例详细描述了CORS系统的建成及其在勘测定界中具体应用。

Continuous operation reference station （CORS） technique, which integrates computer-network management technology, internet technology, wireless communication technology and GPS technology, combines the most advanced multi-reference stations network RTK algorithms and represents the research direction of the new generation of positioning technology following the conventional RTK technology. The paper introduces the building and utilization of CORS particularly by taking the surveying and demarcation of Xi＇an Railway Administration as the example.
