| Abstract: | Harbin GNSS bi-satellite navigation system was completed and put into operation.The basic principle of network RTK is based on Virtual Reference Station(VRS)technique.By real-time differential GPS surveying for ultra-short baseline,it can acquire the location information with better accuracy.The covering area of network RTK reached 140 000 square kilometers.Compared with traditional RTK surveying technique,network RTK has the advantages of wide covering scope,high accuracy,simple operation,etc.It is widely applied in urban planning surveying. |
