Satellite communication uses artificial satellites to relay signals between distant points on Earth, enabling global coverage for broadcasting, navigation and data.
It is essential where terrestrial infrastructure is impractical, such as oceans, remote regions and aviation.
Satellites operate in different orbits: Geostationary (GEO) satellites stay fixed over one point and provide wide coverage; Medium and Low Earth Orbit (MEO, LEO) satellites are closer, offering lower latency for navigation and broadband constellations.
A ground station sends an uplink signal to the satellite, which amplifies and shifts the frequency through a transponder before sending a downlink signal back to receivers.
