THE KINEMATIC POSITIONING OF VEHICLE WITH REAL-TIME DIFFERENTIAL GPS/GLONASS AND REAL-TIME KINEMATIC GPS/GLONASS

摘要

Nowadays GPS(Global Positioning System) plays a important roles in the land navigation system, but, it doesn't determine the kinematic positions of vehicles accurately because of few satellites tracked in the urban canyon covered with trees and high buildings. So GLONASS(GLObal Navigation Satellites System), the Russian satellites' system, operated in 1996, was introduced to overcome these drawbacks. So this study deals with the kinematic positioning of vehicle with Real-Time Differential Positioning using code phase and Real-Time Kinematic positioning using carrier phase. As a result, it was shown that the accuracy of the kinematic positioning of vehicle with the integrated GPS/GLONASS is better than that of GPS stand-alone by high acquisition rate of the differential corrected positions and autonomous positions.
