Abstract:
1. A method for conducting communications via a satellite comprising: using an antenna subsystem of the satellite to provide a plurality of fixed location spot beams in a hub-spoke spot beam satellite communication system, the spot beams being assigned to beam groups according to an objective; sequentially switching at least one transmit-side switch associated with the first pathway to connect an output of the first pathway with different spot beams within the first beam group to establish traffic between a gateway and at least one user terminal, according to a first transmit beam switching pattern; sequentially switching at least one transmit-side switch associated with the second pathway to connect an output of the second pathway with different spot beams within the second beam group to establish traffic between a gateway and at least one user terminal, according to a second transmit beam switching pattern; coordinating the first transmit beam switching pattern and the second transmit beam switching pattern to avoid substantial interference between traffic transmitted to a spot beam of the first beam group on a same frequency as traffic transmitted to a spot beam of the second beam group.
