> GPS satellites don't send down a location, they only send down time They do send a location - to be more exact, they send rough locations of all satellites in the constellation (almanac) and precise location of themselves (ephemeris). Devices like mobile phones, however, usually get that data from other sources because it's much faster than listening to data over GPS.
