Telematics is the convergence of telecommunications and information processing. The term has come to refer to automation in automobiles, such as the invention of the emergency warning system for vehicles. GPS navigation, integrated hands-free cell phones, wireless safety communications and automatic driving assistance systems all are covered under the telematics umbrella.

Vehicle tracking allows monitoring the location, movements, status and behaviour of a vehicle or fleet of vehicles. This is achieved through a combination of a GPS (GNSS) receiver and an electronic device (usually comprising a GSM GPRS modem or SMS sender) installed in each vehicle, communicating with a user (dispatching, emergency or co-ordinating unit) and PC-based or web-based software.

Vehicle tracking systems may also use odometry or dead reckoning as an alternative or complementary means of navigation.

GPS tracking is usually accurate to around 10–20 metres
