Analysis on Data Processing and Accuracy Evalution for High-Speed Railway CPI Plane Control Network
摘要
Abstract
The precision engineering plane control network has become an important part of high-speed railway construc-tion,and the accuracy plays a decisive role in the subsequent construction.Based on a CPI plane control net-work of one high-speed railway as an example,this paper introduced the retest scheme,analyzed the require-ments and methods of GNSS field data collection and internal data processing,and evaluated the measure-ment accuracy by using the poor coordinates and relative accuracy index of poor coordinates,measurement achievement were compliance with the relevant standards.关键词
