Key Points and Result Analysis of Precision Control for GNSS Control Network of Nanning Metro Line 6
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.
