基于单基站的航运CORS系统动态精度测试与分析

Analysis of Dynamic Precision Test on Single Base Station in Navigation CORS System

在长江干线全线建立了某航运CORS系统,分别采用定点、动态和船载三种模式,对该系统进行了精度及可用性测试,计算并分析了测试数据。结果表明,该系统的精度及可用性均满足设计要求,满足船舶定位导航的需求,可以为长江干线流域的船舶提供实时、动态、高精度的位置服务。

A CORS system serving for shipping was established in mainstream waterway of the Yangtze River aiming at the increasing navigation demand. The precision and availability of this CORS system were tested in the mode of fixed point test,dynamic test and shipborne test,respectively. The test data was computed. Result shows that the precision and availability of the CORS system could reach the design requirements. The navigation CORS system could provide realtime,dynamic and high precision service for the watercraft in the Yangtze River basin.
