  • Method and a system of providing multi-beam coverage of a region of interest in multi-beam satellite communication
    Patent number: 9654201
    Abstract: A method of providing multi-beam coverage of a Region of Interest (ROI) in a multi-beam satellite communication system in which a non-uniform traffic demand density is defined over said Region of Interest, the method including partitioning the Region of Interest into N>1 non-overlapping cells (V1-V10, Vi); and generating N satellite beams, each of the satellite beams providing coverage of a respective cell. The step of partitioning the Region of Interest into N>1 non-overlapping cells is performed in such a way that the traffic demand associated to the cells is substantially uniform. Advantageously, the cells form a Voronoi diagram defined over the Region of Interest, the satellite beams being pointed towards the cells of the Voronoi diagram. A satellite communication system implementing the method is also provided.
