| Abstract: | Real-time positioning and dynamic positioning are the key problems of precise point positioning.Based on the real-time track and clock correction product,the mathematical model and error processing method of GPS/BDS real-time precise point positioning are discussed in this paper. Embedded hardware and software platform is built and an embedded device with real-time GPS/BDS dual system,high-precision positioning function is developed. Test results show that for embedded GPS/BDS real-time precise point positioning,the horizontal direction is better than 3 cm and the elevation direction is better than 8 cm under static conditions,the plane direction is better than 12 cm and the elevation direction is better than 15 cm under dynamic conditions. |
