Abstract: A method for allocating frequencies in a multibeam satellite radiocommunications system is provided, wherein a geographical service zone covered by the system is broken down into a plurality of cells, distributed into a first grid and a second grid of cells, the cells of the first grid and the cells of the second grid being respectively associated with opposing polarizations of the transmission signals; a cell is broken down into two parts, one part being respectively associated with a colour corresponding to a frequency sub-band and to the polarization of the grid to which it belongs, the total frequency band being broken down into three frequency sub-bands; and two contiguous cell parts of one and the same grid are associated with different colours.
