Real time fleet monitoring and security system using GSM network

Automobile tracking in the private and defense sector has required a vast amount of research and development. This paper presents the two-way multiple vehicles tracking system using GSM network and satellite communication. The multi-vehicle tracking system uses an extensive combination of global positioning system (GPS), GSM network and Digital mapping with cost effective hardware solution. The tracking system works on the synchronization of the vehicle client unit and the base station. Multi-layered digitized maps results real-time and precise location tracking and provides the various detail information of environment. The system is exploited for vehicle security providing opportunity to remote server to secure the vehicle in case of theft with indispensable anti theft device. Moreover the system provides text guidance to the client through embedded LCD and KEYPAD interfacing.
