automobiles, trains, ships...ect. All will eventually be equipped with GPS. Some of the more expensive cars on the market today, are equipped with a system called OnStar ( TradeMarked ) get lost in your car and OnStar can plan a turn by turn route. Have a car accident in a remote location and OnStar will automatically know it's precise position, and call the police and rescue. I can go on and on..pardon the pun.
