Multibeam VSAT for cluster of slightly inclined GSO satellites

A source terminal for communications with a destination terminal, both located near or on earth surface, via a plurality of satellite links to a first cluster and a second cluster of satellites in corresponding slightly inclined Geostationary Satellite Orbits (GSOs), the first and second clusters of satellites are centered on first and second GSO orbital slots respectively as viewed by the source terminal and the destination terminal, the source terminal comprising:

• a transmitter comprising:
• a preprocessor configured to perform a K-muxing transform on M concurrent input data streams to generate concurrently M output data streams, M being an integer greater than 1, each of the M output data streams being a linear combination of the M concurrent input data streams, the K-muxing transform having an inverse transform;
• a bank of modulators configured to transform N of the M output data streams into N signal streams destined for the destination terminal, N being an integer less than or equal to M;
• and
• a multibeam antenna system configured to concurrently and dynamically track and communicate with the first and second clusters of satellites via the plurality of satellite links, the multibeam antenna system transforming the N signal streams into N shaped beams and radiating N1 of the N shaped beams towards the first cluster of satellites and N2 of the N shaped beams towards the second cluster of satellites, N1 and N2 being positive integers and N1+N2=N.
