Automatic Vehicle Location (AVL)

Automatic Vehicle Location (AVL) is a method used for determining the location of a vehicle on the earth’s latitude and longitude coordinates.

The most common means of determining AVL is by data received from the Global Positional System (GPS). Other methods for determining location are dead reckoning, inertial navigation, or Radio Frequency Identification (RFID) readers; sometimes a combination of these methods can be used.
