Assignee: TELESAT TECHNOLOGY CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A satellite communications system comprising:
a set of satellites in a LEO (low Earth orbit) constellation;
a user terminal for transmitting to, and receiving signals from, said set of satellites; and
a Gateway tear transmitting to, and receiving signals from, said set of satellites;
at least one of said set of satellites being operable to:
transmit and receive signals via a Wide Area Coverage beam;
receive a request from the user terminal for high-capacity beam coverage; and
respond to receiving the request from the user terminal for high-capacity beam coverage by switching the user terminal to a higher bandwidth, narrow, steerable beam, pointed towards the requesting user terminal;

wherein the Gateway is operable to avoid interference with a GEO satellite user terminal by switching the Gateway to an alternate LEO satellite that has an angular separation with a GEO satellite greater than a calculated discrimination angle, as measured at the GEO user terminal.
