Abstract
A method for multibeam coverage of a region of the surface of the Earth includes the generation, by a telecommunications payload embedded on a satellite, of a plurality of radiofrequency beams, called elementary beams; the formation of a plurality of radiofrequency beams, called composite beams, exhibiting footprints on the ground of different sizes, each the composite beam being obtained by the grouping of one or more elementary beams; and the transmission or the reception of data through the composite beams, identical data being transmitted or received through all the elementary beams forming one and the same composite beam.

A method for multibeam coverage of a region of the surface of the Earth comprising:
- the generation, by a telecommunications payload embedded on a satellite, of a plurality of radiofrequency beams, called elementary beams;
- the formation of a plurality of radiofrequency beams, called composite beams, exhibiting footprints on the ground of different sizes, each said composite beam being obtained by the grouping of one or more elementary beams;
- and
- the transmission or the reception of data through said composite beams, identical data being transmitted or received through all the elementary beams forming one and the same composite beam;
- wherein at least one said composite beam is formed by the grouping of a plurality of elementary beams of different colours, a colour being defined by a frequency band and a polarization state.
