This project presents a vehicle tracking system using GPS and GSM technology. The system tracks a vehicle's location via GPS and sends the coordinates as an SMS to the owner on request. It can also be connected to a car alarm to alert the owner by SMS if the alarm is triggered. The low-cost system consists of a GPS receiver, microcontroller, and GSM modem to process location data from satellites and send it via text message. It provides an affordable solution for monitoring vehicles and detecting theft.

MICRO CONTROLLER BASED TWO WHEELER THEFT CONTROLLERS
ABSTRACT
This Project presents an automotive localization system using GPS and GSM- SMS
services. The system permits localization of the automobile and transmitting the position to
the owner on his mobile phone as a short message (SMS) at his request.
The system can be interconnected with the car alarm system and alert the owner on
his mobile phone. This tracking system is composed of a GPS receiver, Microcontroller and a
GSM Modem. GPS Receiver gets the location information from satellites in the form of
latitude and longitude.
The Microcontroller processes this information and this processed information is sent
to the user/owner using GSM modem. The presented application is a low cost solution for
automobile position and status, very useful in case of car theft situations, for monitoring
adolescent drivers by their parents as well as in car tracking system applications. The
proposed solution can be used in other types of application, where the information needed is
requested rarely and at irregular period of time (when requested)
This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the
ac output of secondary of 230/18V step down transformer.
