CORS在浮动车交通信息采集系统中的应用

Application of CORS to floating vehicle traffic information acquisition system

针对目前GPS浮动车交通信息采集系统中GPS原始数据因精度产生的问题,在深入分析CORS系统的基础上,提出结合CORS系统,对浮动车采集数据进行实时差分改正的优化方案。CORS与GIS结合对综合信息进行输入,将能大幅度改善数据的准确性,提高数据的利用率,实现数据质量的优化。

In view of accuracy problems of GPS raw data in the current GPS floating vehicle traffic information acquisition system, after in-depth analysis of the continuous operating reference station （CORS system）, an optimization scheme for real-time differential correction of floating vehicle data acquisition based on CORS is proposed. CORS combined with GIS in the input of comprehensive information, can greatly improve the accuracy of data, improve the utilizati-on of data and optimize the data quality.
