Research on the Construction of METRO First Class Control Network in Exceptionally Large Area

LIU Min;  
The characteristics of large regional rail transit control network such as covering a wide area, long lines, long time span, large work intension, which was discussed in this paper. Guangzhou City track GPS control network construction was taken as the breakthrough point, and our purpose was building a high precision rail transit GPS control network in exceptionally large area by combining with the existing lines, long-term planning, overall planning, and careful designing, which successfully resolved the large area of several major problems on network construction of city orbit trai c primary control. And the establishment of city rail transit GPS control network will greatly promote the application and popularization of the surveying and mapping results in the city infrastructure construction, and raise the level of social service of City Surveying and Mapping departments.
