Satellite-based System
A satellite-based system is a system that uses one or more satellites to provide services or information to users on the ground or in the air. In aviation, satellite-based systems are used for a variety of purposes, including navigation, communication, surveillance, and weather monitoring. One example of a satellite-based system used in aviation is the Global Positioning System (GPS), which provides accurate position and velocity information to aircraft and ground-based users. Another example is the Automatic Dependent Surveillance-Broadcast (ADS-B) system, which uses satellites to broadcast an aircraft's position, altitude, and other information to other aircraft and air traffic control. Satellite-based systems have revolutionized aviation by providing more accurate and reliable information to pilots and air traffic controllers, improving safety and efficiency.
