摘要
以南宁轨道交通6号线控制网为研究对象,论述和总结了6号线GNSS控制网建网过程中的技术路线和实施要点,详细介绍了网形设置、观测时间窗口、起算点的选取与稳定性分析以及数据处理等精度控制方法,并通过联测换乘线路和先行试验站的重合点来确保6号线与其他系统相对关系的兼容与稳定,最后对结果进行了分析.
Abstract
Taking the control network of Nanning Metro Line 6 as the research object,this paper discusses and summarizes the technical route and implementation points in the process of building the GNSS control network of Line 6.It provides a detailed introduction to precision control methods such as network shape setting,observation time window,selection and stability analysis of starting points,and data processing.Through joint measurement of the intersection points of transfer lines and pilot test stations,it ensures the compatibility and stability of the relative relationship between Line 6 and other systems,finally,the results were analyzed.
