| 摘 要： | CORS系统中的网络RTK技术是GPS—RTK技术的进一步延伸，采用网络通讯延伸了RTK的作业半径，具有明显的经济型与高效性。湖北省CORS系统于2010年12月全面建成，并投入使用，该系统覆盖湖北全境，可对湖北全境及周边地区用户自动提供经过检验的不同类型的GPS观测值、各种改正数、状态信息以及其他GPS服务项目。本文结合工程实例，详细介绍了湖北CORS系统在长江中下游河段固定断面测量中的具体应用。

| Abstract: | Network RTK technology in CORS system is a further extension of GPS - RTK technology and the operation radius of RTK is extended by the network communication, which is economical and efficient. System of CORS of Hubei province was fully completed in December 2010 and put into use. The system covers the whole territory of Hubei to automatically test different types of GPS observa- tions, various corrections, state information and other GPS services to users throughout Hubei and the surrounding areas. Combining with the engineering example, the paper introduces in detail the application of CORS system in fixed section measurement of the mid- dle and lower Yangtze River in Hubei. |
