Car Gps / Dead Reckoning (dr) / Electronic Map Integrated Navigation System

Integrated navigation system is the trend of land vehicle navigation and positioning, the development of GPS/DR/Electronic-Map integrated navigation system for vehicle is proposed in this paper. Through analyzing the whole system, integrated system are designed according to the thought of structured design in this paper.The following three questions are discussed in the paper: GPS navigation data is collected and disposed; How to use Electronic-Map in the GPS/DR integrated navigation system, An algorithm of map-matching based on the projection is discussed emphasizly; Data Fusion of GPS/DR/Electronic-Map integrated navigation system, Applied the information fusion on GPS/DR integrated navigation system, The paper adopts a simple, useful federated Kalman filtering algorithm to fuse the data collected from the sensors of GPS and DR. The ability of high accuracy, real-time positioning can be obtained.
