Global Positioning System
From Tardis Wiki, the free Doctor Who reference
A GPS (Global Positioning Service[additional sources needed]) was a device that determined your location and provided navigational directions.
Geoff Bluth was driving in a snowstorm when his GPS failed. He called his hotel for directions, but was abducted by an odd man in a pinstriped suit and bowler hat. (PROSE: Attack of the Snowmen)
