Multibeam VSAT for cluster of slightly inclined GSO satellites

A system for communications between a source terminal and a destination terminal, both located near or on earth surface, via a plurality of satellite links to a cluster of satellites in corresponding slightly inclined Geostationary Satellite Orbits (GSOs), the satellites moving in northward and southward directions mostly centered on a first GSO orbital slot as viewed by the source and the destination, the system comprising:

• 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 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 first multibeam antenna system configured to dynamically track and communicate with the cluster of satellites via the plurality of satellite links, the multibeam antenna system transforming the N signal streams into a plurality of shaped beams and radiating the shaped beams towards the cluster of satellites.
