Classification: CPC H | IPC H

Claim 7:
8. A method of operation for a satellite communications system comprising:
launching a set of satellites in a LEO (low Earth orbit) constellation;
using a user terminal, transmitting to and receiving signals from said set of satellites;
using a Gateway, transmitting to and receiving signals from said set of satellites;
at least one of said set of satellites:
transmitting and receiving signals via a Wide Area Coverage beam;
receiving a request from the user terminal for high-capacity beam coverage; and
responding 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; and

avoiding 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 satellite user terminal.
