A GPS tracking unit is a device, normally carried by a moving vehicle or person, that uses the Global Positioning System to determine and track its precise location, and hence that of its carrier, at intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location database, or Internet-connected computer, using a cellular, radio, or satellite modem embedded in the unit. This allows the asset’s location to be displayed against a map backdrop either in real time or when analyzing the track later, using GPS tracking software.
