Performance Improvement of GPS/DR Car Navigation System Using Vehicle Movement Information

摘要: This paper describes performance improvement of GPS/DR Integration system using area decision algorithm and vehicle movement information. In GPS signal blockage area, i.e., tunnel underground parking DR sensor errors are accumulated navigation solution is gradually diverged. We use the car information according to moving correct error. Also, decided as stop, straight line, turn changing region through data analysis. The experiment performed verify supposed method. results show that method provides small position heading error than previous
