satellite networks
Space-based broadcasting systems
Satellite networks are communication systems that relay signals through artificial satellites orbiting Earth.
They enable broadcasting, internet access, and data transmission across vast distances, reaching areas where ground-based infrastructure is impractical: Remote villages now have internet through satellite networks.
The term covers both the satellites themselves and the ground stations that coordinate with them.
