GPS Relay

Install GPS receivers on cell towers and triangulate.
  [vote for,

Cell companies should install GPS receivers on cell towers and using triangulation relay GPS location data to cell phones. This would be an inexpensive way to bring GPS functionality to everyday cell phone users.

       Cellphone towers don't need a GPS to tell them roughly where they are. They're always in exactly the same place as they were built! (Except for maybe Californian ones, which might end up closer to the seabed one day...)

       Those moving ones are faulty towers.

       Cell phones are already required (US only, as far as I know) to have location data available to 911 services. They may not have met the deadline, but the requirement is there. My phone (two years old at Easter) has GPS. The part that really ticks me off is that I can't get at the location data. Only E911, and probably sprint, can see the data.   

       Oh, and the phone recieves signals straight from the satellites, but uses the network to determine location.

       But there's no E911 emergency location service for lost towers yet.

       Er... already done without the relay. 3G cellphones use the GPS information from phone masts rather than satellites to determine their location.
