=== Vehicle tracking ===
[[Vehicle tracking]] is monitoring the location, movements, status, and behavior 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 the user (dispatching, emergency, or co-ordinating unit) and PC-based or web-based software. The data is turned into information by management reporting tools in conjunction with a visual display on computerized [[map]]ping software. Vehicle tracking systems may also use [[odometry]] or [[dead reckoning]] as an alternative or complementary means of navigation.{{Citation needed|date=September 2017}}
