CORS卫星定位综合服务系统在杭州市水利测量中的应用

Application of CORS in Water Measurement in Hangzhou

CORS系统是卫星定位技术、计算机网络技术、数字通讯技术等高新科技多方位、深度结晶的产物.杭州市卫星定位综合服务系统包括9个GPS参考站1个数据中心,由基准站网、数据处理中心、数据传输系统、定位导航数据播发系统、用户应用系统组成.在为杭州市城市防洪减灾规划提供河道断面和为建立模型提供三维数据基础资料的运行中,达到垂直定位8cm的快速定位精度,极大地提高了作业效率,减少了测量成本.

CORS System is the product of high-technology, such as satellite positioning technology, computer network technology and digital communication technology with great ease and rapidity to various measurements around the city. Hangzhou Satellite Integrated Service System and the working principles of CORS are briefly introduced in the paper, combined with the practical application of the system in Hangzhou city flood control and disaster mitigation planning. The elevation accuracy of the system in the water measurement is also analyzed, and some conclusions are drawn.
