A GPS navigation system is a GPS receiver and audio/video (AV) components designed for a specific purpose such as a car-based or hand-held device or a
smartphone app.
The global positioning system (GPS) is a 24-satellite navigation system that uses multiple satellite signals to find a receiver’s position on earth. GPS was
developed by the U.S. Department of Defense (DoD). The technology was originally used for military purposes. Since 1980, when GPS technology was made available to the consumer market, it has become common in cars, boats, cell phones, mobile devices and even personal heads-up display (HUD) glasses.
GPS
receivers find their location by coordinating information from three or four satellite signals. That information includes the position of the satellite and the precise time of transmission. With three signals, any 2D position can be found on earth; additional satellite signals make it possible to find altitude.
GPS technology works in almost any condition and is accurate to within 3-15 meters, depending on the number of signals received, the spread of satellites in the sky and the
technologies used in the receiver.

| Welcome to the Dauntless Aviation Glossary! At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can
find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning
environments and world's best and clearest content (please do give them a try.).

| A Global Navigation Satellite System (GNSS) navigation system that can determine position and track the movement of an aircraft. A global positioning system (GPS) receiver must be installed on board the aircraft to receive and interpret signals from the satellite-based system.

| The Global Positioning System is a series (or “constellation”) of satellites circling the Earth, each broadcasting a unique signal. These signals, usually three or more, are detected by electronic units, and, thru triangulation and time delay sensings, provide an extremely accurate location readout of the GPS receiver. Many balloon pilots carry a small GPS unit on board the balloon to determine location, ground track and ground speed.

|
| A space-base radio positioning, navigation, and time-transfer system. The system provides highly accurate position and velocity information, and precise time, on a continuous global basis, to an unlimited number of properly equipped users. The system is unaffected by weather, and provides a worldwide common grid reference system. The GPS concept is predicated upon accurate and continuous knowledge of the spatial position of each satellite in the system with respect to time and
distance from a transmitting satellite to the user. The GPS receiver automatically selects appropriate signals from the satellites in view and translates these into three-dimensional position, velocity, and time. System accuracy for civil users is normally 100 meters horizontally.
