Satellite Communications System
Also known as: satellite communications system
Definition
A satellite communications system is an integrated set of spacecraft, ground infrastructure, terminals, and links used to transport communications traffic through space-based assets.
Key Points
- Includes space, ground, and user-terminal elements.
- Supports wide-area and hard-to-reach connectivity.
- Can deliver broadcast, backhaul, mobility, or direct user services.
- Performance depends on orbital geometry, spectrum, and link design.
Concept
It is the operational system behind satcom service delivery, not just a satellite or a radio link.
Explainer
The term covers the end-to-end service architecture. A satellite alone is not the system; the system includes the supporting ground and user segments needed to make the service work.
