A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with software that collects this fleet data for a comprehensive picture of vehicle locations. IDS will soon launch a vehicle tracking system that will commonly use GPS technology for locating the vehicle. Vehicle information can be viewed on electronic maps via the Internet or specialized software.
Many modern vehicle tracking devices combine both active and passive tracking abilities; when a cellular network is available and a tracking device is connected, it transmits data to a server. When a network is not available the device stores data in internal memory and transmits stored data to the server when the network becomes available again.
