The Global Positioning System (GPS) consists of 32 satellites in different orbits around the world. At any given time a number of satellites are in view in any place on the earth. A GPS receiver receives information from these satellites and uses it to locate it. Though it requires 3 satellites to find the latitude and longitude of the receiver’s position, it needs another satellite signal to calculate the altitude.
Automatic Vehicle Locating (AVL) :- It is anoffshoot of GPS vehicle tracking technology an advanced method of remote vehicle tracking and monitoring. As per the scheme of things for using the Automatic Vehicle locating, the targeted vehicle is equipped with an AVL unit that receives signal from the GPS satellites. The GPS receiver determines its current location, speed and heading which is stored locally for eventual analysis or transmitted to a central control center using GSM- Global standard of mobile communication or other suitable wireless technology. By a combination of these technologies you can protect and monitor your mobile assets like car, truck, bike, boat or ship virtually anywhere and then locate it within a few meters. The central tracking station monitors your vehicle 24 hours per day for unauthorized, intrusion, pilfering, breakdown, accident or even for any unforeseen emergency assistance.
