中文摘要：

GPS定位技术已经被广泛地运用并发展成为一个真正的三维测量工具。GPSCORS系统是GPS的连续运行参考站，是在一个城市、一个地区、或一个国家范围内，根据要求按一定距离间隔，建立常年连续运行的若干个固定GNSS参考站，组成的网络系统。本文通过对GPSRTK测量中遇到的不同坐标系统的分析，阐明了不同坐标系统之间数据转换的本质。结合在生产中使用的GPSRTK设备，说明了WGS--84坐标系向地方坐标系转换的一般过程和注意事项；对GPSRTK测量中遇到的不同坐标系统，进行理论上和实践上的研究，达到了预期效果，掌握了中海达V8GNSSRTK接收机在GPSRTK测量中的使用问题。

英文摘要：

GPS positioning technology has been widely used and developed into a true threedimensional measuring tool. GPS CORS system is GPS continuous operation of reference, is standing in a city, a region, or a nationwide, according to the requirements in a certain distance interval, establish the perennial continuous operating several fixed GNSS reference station, network composed of system. Based on the GPSRTK encountered in measuring the analysiofthedifferentcoordi hate systems, illustrates the data conversion between different coordinate systems of nature. Combination used in the pro duction of GPSRTK equipment, indicating the WGS84 coordinate system transformation to local coordinate system the general process and considerations; on GPSRTK encountered in measuring the different coordinate system, the theoretical and practical research, reaching Expected results, master the zhd V8 GNSS RTK Receiver in GPSRTK the use of meas urement.
