摘要
阐述了CORS系统的基本原理和技术算法,通过2个工程实例对CORS系统的测量成果和铁路勘测控制网的测量成果进行比较,统计分析了精度情况,证实CORS系统平面坐标精度较高、高程精度稍低,但可以满足铁路勘测初测工作的需要,CORS系统独特的测量优势将使CORS系统成为今后铁路勘测的重要手段之一。
In this paper, we described the basic principle and algorithm of CORS system, compared the measurement results of CORS system and railway survey control network through two engineering examples, and statistical analyzed the accuracy. The results show that CORS system has higher accuracy of plane coordinates, and elevation accuracy is slightly lower, but can meet the preliminary survey work needs of railway survey. The unique measurement advantage of CORS system can make the CORS system become one of the important means of railway survey in the future.
