| Abstract: | The GNSS continuously operating reference stations system of Hong Kong-Zhuhai-Macao Bridge is the first independent VRS-based engineering CORS in China.Combining with the engineering environment and project needs,the construction characteristics and technical difficulties were analyzed in the paper.Therefore,the composition,overall structure and essential functions of the CORS,as well as the reference station connecting surveying and the application of the precise quasigeoid,were discussed.Through the analytical results of the real-time kinematic(RTK) satellite navigation of the system,it was showed that the presision of the GNSS network RTK based on VRS excels ±2 cm in horizontal direction and ±3 cm in vertical direction,by which the construcrion goal of the system was realized. |
