An automobile tracking system is an electronic device installed in a automobile to know the owner or a third party to track the automobile location. This paper proposed to design a automobile tracking system that works using GPS and GSM Modules, which would be the less cost source of automobile tracking and it would work as anti-theft system. It is an embedded system which is used for tracking and positioning of any automobile by using Global Positioning System (GPS) and Global system for mobile communication (GSM). This proposed project will continuously monitor a moving Automobile and send the status of the Automobile on user demand. For doing so an Adriano is interfaced serially to a GSM Modem and GPS Receiver. A GSM modem is used to send the position (Latitude and Longitude) of the automobile from a place where the automobile is actually there. The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the automobile to the Adriano. The same data is sent to the Adriano continuously when it gets the request from the user. If the owner wants to track the automobile he has to send the request to the Adriano using the GSM Module. When Adriano get the request then it send the current position of the automobile to the registered numbered through the GSM Module.
