communications satellites
Space-based signal transmitters
Communications satellites are spacecraft orbiting Earth that relay signals between ground stations, enabling long-distance transmission of television, radio, telephone, and internet data.
They function as relay towers in space, receiving signals from one location and retransmitting them to another: The game was broadcast via communications satellite to viewers worldwide.
Geostationary satellites remain fixed over one point; others orbit in constellations.
