The satellites that provide SBB services are called I-4 satellites. At the time of publishing,
three I-4 satellites provide SBB services: Americas (98W), EMEA (25E) and Asia-Pacific
(143.5E).

The HSD-Xi terminal extends the communication functions provided by other HSD terminals.
It does not communicate with the satellite network on its own. It must be installed with a HSD
to communicate with the satellite network.
