•A GPS navigation device is any device that receives Global Positioning System
(GPS) signals for the purpose of determining the device's current location on
Earth. GPS devices provide latitude and longitude information, and some may also
calculate altitude, although this is not considered sufficiently accurate or continuously available enough to rely on exclusively to pilot aircraft. GPS devices are used in military, aviation, marine and consumer product applications.

How Does a GPS Receiver Work?
•GPS receivers use the satellite-based Global Positioning System (GPS). The U.S.
Department of Defense operates the GPS, which relies on a worldwide network of
satellites that constantly broadcast signals from space to the ground. Your
receiver determines its position by combining the transmission data from 4 or
more satellites.
