Web-based vehicle localization

The development of wireless communications and the growing computational power of mobile devices reduces the difference between desktop and mobile computing environments. In this paper we present an embedded vehicle localization system which is developed on technologies commonly used in desktop applications. The architecture of our system is a client-server one. It is Web-based system. All data are presented to the user through a Web browser interface. They are processed locally by Java applets or on the server by Java applications. Data are accessed through common Internet connections: TCP/IP or higher level protocol like HTTP. Our system uses differential GPS for localization of vehicles and cellular phone for communication with data servers. It integrates the possibility to send differential GPS corrections through the Internet connection
