Abstract:
A satellite telecommunications system has a global coverage area and a plurality of user terminals distributed in the global coverage area. The global coverage area is covered by a first set of spots which form a regular cellular mesh, and by at least a second set of local spots, irregularly distributed and superimposed geographically on spots of the first set. The spots of the first set of spots have allocated channels with the same frequency capacity, the same channel being re-used by a plurality of different spots, and the local spots of the second set of spots have a special allocated channel having an increased frequency capacity.
