About GPS Technology

The Global Positioning System (GPS) is a tracking and navigation system developed by the
U.S. Department of Defense. The system uses 24 satellites that orbit the earth, sending out
radio waves that can be picked up by GPS sensors (hardware devices for receiving data).
Normally, a GPS sensor relies on receiving signals from four satellites simultaneously to
track its position. Each signal contains an identifier for the satellite that emitted it and the
exact time it was emitted (to the nanosecond). GPS relies on the fact that radio waves travel
at the speed of light to calculate distances and the exact location of the sensor is figured by
combining the data received from three or four satellites.
Given the right conditions, a GPS sensor can identify your geographic position anywhere in
the world. GPS is able to give you the latitude, longitude and elevation of your present
location, as well as your road speed and direction of travel on a route.
