satellite communication
Space-based transmission
Satellite communication is the transmission of signals between points on Earth using artificial satellites as relay stations in orbit.
Voice calls, television broadcasts, internet data, and GPS signals all travel via satellite links, especially when ground-based infrastructure is impractical or unavailable.
The technology enables global coverage, connecting remote areas, ships at sea, and aircraft in flight.
Satellite communication made live international broadcasts possible.
