Just how does Vehicle Locating/Tracking work?

AVL (Automatic Vehicle Locating or Vehicle Tracking) utilizes the triangulation of 3 or more Global Positioning Satellites (GPS) to send Latitude/Longitude information back to a central location.  The GPS system consists of satellites whose paths are monitored by ground stations. Each satellite generates radio signals that allow a receiver to estimate the satellite location and distance between the satellite and the receiver. The receiver uses the measurements to calculate where on or above the Earth the user is located.  There are many different types of Vehicle Locating systems to choose from including Passive, Cellular and Satellite Tracking Systems.
