Research And Design For GPS/DR/GIS Intergrated Vehicle Navigation System

Intelligent vehicle positioning and navigation system is a typical representation of new type electronic productions on vehicle. Its application greatly alleviated the trouble of city transportation system and improved the efficiency of road. Integrated navigation system is the trend of land vehicle navigation and positioning, the development of GPS/DR/GIS 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 some problems are discussed in the paper: how to use Electr-onic-Map in the GPS/DR integrated navigation system, an algorithm of Map-Ma-tching is designed; information fusion of GPS/DR/GIS integrated navigation sys-tem, neural network technique is used to information fusion. The paper designs a simple, useful federated Kalman filtering to fuse the data collected from the sensors of GPS and DR. The ability of high accuracy, real-time positioning canbe obtained.GPS/DR/GIS vehicle navigation system concerns to widespread technique field. This paper use the advanced embedded system technique, basing on the platform of Microsoft's Wince.Net and SamSang's s3c2410, coordinate the corresponding outside components. Researching and developing the system platform's OS and broad support package (BSP).BSP is the important basic and key of OS core transplant and system application software. Finally, drive programs of the system be designed in the laboratorial board that a entire platform be provided for upper navigation software and application software.
