When called, sends out a ping to any listening GPS hosts, which in turn will send their own coordinates. Using these coordinates and the signal distance, using trilateration the GPS api can acquire its own location. If for any reason the GPS locating failed, the returned x, y and z will be nil. A Wireless Modem must be attached and GPS Hosts must be in range for the GPS location to succeed.
