User Terminals and the Ground Segment
Is the ground side of space systems, user terminals, gateways and antennas, a supply constraint?
Chapter summary
the ground segment is a larger manufacturing business than satellites by unit count, and it has its own bottlenecks.
Key takeaways
- 1
Broadband constellations need millions of flat-panel user terminals built from phased-array chips; each constellation needs gateway antennas and ground stations by the hundred; defence needs hardened terminals for ships, aircraft and vehicles.
- 2
Terminal supply draws on consumer-electronics manufacturing, mostly in Asia, and on the same beamformer and GaN chips as satellites.
- 3
Gateways need sites, permits, fibre and power.
