Fleet tracking is a management system that uses GPS to monitor the activity of tracked assets (vehicles, workers, equipment). It is often referred to as vehicle tracking or AVL. The fleet is generally a collection of land-based assets such as cars, trucks, field workers and equipment (powered and unpowered e.g. trailers).
Fleet tracking uses telematics technology to collect data from a fleet of assets. This data is normally collected in real time (actively) so it is more useful for fleet managers, who use the data to make strategic decisions about operations (which vehicle should I dispatch to a new job, where is the nearest crane, how many generators do we have in the yard, has my lone worker returned from the jobsite etc.)
For fleet tracking to be effective you need fleet tracking software that intelligently interprets the huge amount of data coming in from the fleet, and converts it into easy-to-use reporting dashboards and exception alerts.
