Automatic vehicle location

Automatic vehicle location (AVL) is a method for automatically determining and transmitting the geographic location of a vehicle. This data can be used to create a vehicle tracking system, which is a component of fleet telematics and various location-based services in the Internet of Things (IoT) ecosystem.

The most common method for determining location is through the use of a GNSS receiver (such as GPS), which collects positioning data from satellites. This data is then transmitted via a wireless network, typically a cellular network or satellite communication system, to a central server. The server processes this information and makes it available for several applications, from dispatching emergency vehicles to providing real-time arrival information for public transport. AVL is often integrated with other vehicle systems to collect a wider range of data as part of telematics.
