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.
