GSM and GPS based Vehicle Navigation and Tracking





     This project is an embedded system application which tracks the vehicle using Global Positioning System (GPS) and Global System for Mobile communications (GSM).The system has two units, the VEHICLE UNIT and BASE MONITORING UNIT. The VEHICLE UNIT consists of GPS and GSM modems, which are interfaced by a MICROCONTROLLER.

        The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the vehicle. The GSM modem is used to send the position (Latitude and Longitude) of the vehicle from a remote place to the BASE MONITORING UNIT.

       The Microcontroller is interfaced serially to a GSM Modem and GPS Receiver and is used for interfacing to various hardware peripherals.

       The BASE MONITORING UNIT consists of a computer to which a GSM modem is connected to its serial port. When a request by user (GSM mobile) is sent to the number at the VEHICLE UNIT (GSM modem), the system automatically sends a reply to the user which consists of position co-ordinates of the vehicle. The Latitude and Longitude values are interpreted by software and the location of the vehicle is indicated on GOOGLE MAPS.
