How do GPSs work?
GPSs are affixed to vehicles, loads and other items by various means such as magnets, wire ties, tape, velcro, etc., and they locate on a dozen satellites circling the earth, developed for the military, and report by cell technology to a web site the GPS location within about 15 meters, which web site is accessed by the owner PI from the office or vehicle, and analyzed for value and action as appropriate.
