Global Positioning System
(redirected from Selective Deniability)

   Also found in: Encyclopedia, Wikipedia 0.01 sec.
Glob·al Positioning System  (glbl)
n. Abbr. GPS
A system of satellites, computers, and receivers that is able to determine the latitude and longitude of a receiver on Earth by calculating the time difference for signals from different satellites to reach the receiver.

global positioning system
n
(Mathematics & Measurements / Navigation) a system of earth-orbiting satellites, transmitting signals continuously towards the earth, that enables the position of a receiving device on or near the earth's surface to be accurately estimated from the difference in arrival times of the signals Abbreviation GPS

Global Positioning System  (glbl)
A system of satellites combined with receivers on the Earth that determines the latitude and longitude of any particular receiver through triangulation. The distance of the receiver to three of the satellites is ascertained by measuring the time-delay of a predetermined radio signal (called a pseudo-random code). Errors in timing can be corrected by checking the signals against the signal from a fourth satellite. Current systems can pinpoint the location of the receiver with an accuracy of around 5 m (16 ft). The system is used for navigation, surveying, and many other applications. Compare loran.

Global Positioning System
Signals received from four satellites are used to determine the three-dimensional position of the receiver (vehicle). The receiver interprets the arrival times of the signals in terms of latitude, longitude, and altitude.

A satellite constellation that provides highly accurate position, velocity, and time navigation information to users. Also called GPS.
