GPS Cell Phone

What makes a cell phone a GPS cell phone? The first requirement is a GPS receiver either built into the handset or connected to the phone by a USB wire or by a wireless Bluetooth connection. GPS signals originate simultaneously from three or more satellites orbiting about 11,000 nautical miles above the earth. The GPS receiver and GPS software sort out the signals from the different satellites and pinpoint the receiver’s location on the surface of the earth to within a few yards, sometimes closer.

Your smartphone can show your location on your GPS cell phone, the route to your destination, and speak voice directions to help you get there.
