In view of the accuracy and reliability of control points of provincial continuously operating reference stations(CORS) network in long-distance canal control network,a comparative analysis is carried out.On the basis of the Pinglu Canal project and control points established by the provincial CORS network,we use the traditional global navigation satellite system(GNSS) static networking method to test the plane coordinate accuracy of control points calculated by the provincial CORS network,and use the third-class leveling results to test the precision of the quasi-geoid elevation results calculated by the CORS network.The results show that the precision of plane coordinates calculated by the CORS network is accurate and reliable,and the precision of quasi-geoid elevation can reach the root level.This method not only has high operating efficiency,but also has good economic benefits,and has guiding significance for follow-up control network measurement methods in similar long-distance canal construction.
