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.
An Automatic vehicle location system (AVLS) typically functions in three stages: position determination, data transmission, and data integration.
First, a device in the vehicle, typically a GPS tracking unit, determines its geographic coordinates. Most systems use a GNSS (Global Navigation Satellite System) receiver. The receivers calculate their position by processing signals from satellite constellations, such as the United States' GPS, Russia's GLONASS, or Europe's Galileo. In urban environments where satellite signals may be obstructed by buildings, this positioning data can be supplemented with other methods like cellular triangulation or Wi-Fi positioning to maintain a location fix.
Second, the AVL device, often a telematic control unit, transmits this telemetry data to a central server. The two primary methods of transmission are:
Third, a backend server receives and processes the vehicle location data. This server stores the information and makes it available to software applications through an API (Application Programming Interface). The data is analyzed to support management decisions. This allows a fleet management platform to display a vehicle's position on a map or a public transport application to provide passengers with real-time arrival predictions.
Automatic vehicle location has several applications across commercial, public, and consumer sectors.
A common application of AVL is in commercial fleet management, which uses fleet digitalization to monitor and manage vehicles. AVL enables a fleet telematics system to function. It is used to:
