Satellite navigation - Wikipedia
A satellite navigation or satnav system is a system that uses satellites to provide autonomous geopositioning. A satellite navigation system with global coverage is termed global navigation satellite system (GNSS).
Satellite Navigation - Global Positioning System (GPS)
The Global Positioning System (GPS) is a space-based radio-navigation system consisting of a constellation of satellites broadcasting navigation signals and a network of ground stations and satellite control stations used for monitoring and control.
Global Positioning System - Wikipedia
The Global Positioning System (GPS), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States Space Force and operated by Mission Delta 31. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where ...
GPS | Definition, Types, Uses, & Facts | Britannica
GPS, space-based radio-navigation system. A GPS receiver operated by a user on Earth measures the time it takes radio signals to travel from four or more satellites, calculates the distance to each satellite, and from this calculation determines the user’s position.
