Global Positioning System (GPS)


Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. GPS is widely used in aviation for navigation, approach and landing, and aircraft tracking. It provides accurate and reliable information to pilots, air traffic controllers, and ground personnel, enhancing safety and efficiency in air transportation.
