Real Time Vehicle Tracking System

 Automatic Vehicle Location (AVL) is an advanced method used to track and monitor any remote vehicle equipped with a software unit that receives and transfers signals through GPS satellite. AVL is a combination of Global Positioning System (GPS) and Geographic Information System (GIS) that provides actual geographic real time position of each vehicle. The entire transmission mechanism of AVL setup depends on GPS satellite, a receiver on the vehicle, a radio system and controller based tracking for dispatch. The radio communication system is generally the same as cellular phone network. The two most common AVL systems are like GPS based and Signpost based. The Signpost-based AVL system was used earlier but with the development of modern satellites GPS used technology is more use now.

This Automatic Vehicle Tracking system is now widely used in a variety of market system that offers excellent communication or vehicle tracking solution. This project is aimed to track the vehicles that which mean to locate the position of the vehicle. The location of the vehicle is indicated using GPS (global positioning system) technology. Communication link is made possible through a GPS receiver. GPS will give the information of parameters like longitude, latitude and attitude. With this system we can easily identify vehicle thefts. Here the communication takes place between GPS receiver and GPS satellite. GPS satellite continuously tracks the missing vehicle and the position of the vehicle is send to the controller from GPS receiver. Vehicle is associated with LCD display which sends the continuous information about the position of the vehicle to the control unit.and the vehicle position should be send to the GSM.
