“Use of space-borne positioning and timing data is now
commonplace, in everything from freight movement to synchronisation
of computer networks. Cellular and data networks, shipping and air
transport, financial systems, railways, agriculture, and the
emergency services all make frequent use of GPS. There are also
many different recreational uses of GPS. The one that first springs
to mind is for tracking in motor vehicles. GPS helps drivers find
the best route to a specified location, summon help in the event of
an emergency, plot the location of the vehicle on a map, or find
the nearest bank.”
