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.
