Currently , with the fast development of GPS technique , GPS RTK is rapidly being applied to the ca- dastral survey. GPS RTK technique not only improves efficiency and accelerates the rate of mapping , but also increases economic efficiency. The authors introduced a method for GPS RTK rapid positioning , which uses continuous operational reference system ( CORS ) as a base station to change the method of previous map draw- ing by obtaining real-time three-dimensional coordinates of boundary points and statistically analyzing with the three-dimensional coordinates obtained by Total Station to get the accuracy of GPS RTK real-time coordinates. The application of GPS RTK in practical measurement was discussed when the data link had been lost especial- ly. The results show that the three-dimensional coordinates measured by total station can be replaced by real- time three-dimensional coordinates measured by Engineering Star RTK in the CORS.
