Abstract
A satellite communication system is disclosed that utilizes multiple antenna for subscriber terminals to process streams. A first node relays a first stream between the ground station and the subscriber terminals. A second node relays the second lower information rate signal to the subscriber terminals. Spatial relationships are used to differentiate the first stream from the second stream. At least one of the first and second nodes includes a satellite, and the first and second nodes are separated by 50 miles or more. Optionally, frequency ranges for the first and second streams overlap in time. In some cases, the second stream can contain additional information where the second node is terrestrial.
