Patent ID: 8023887

Claim:
A method for dimensioning the supply system belonging to a telecommunication network for establishing radiofrequency links between at least one gateway and ground terminals via a telecommunication satellite having several spot beams, designated as a multispot satellite, the telecommunication network including a service zone including a plurality of cells each including a plurality of ground terminals, the service zone being split into N sub-zones, N being an integer strictly greater than 1, each sub-zone having a capacity profile evolving in time over a given period and presenting a maximum value, the maximum values of each of the capacities being shifted with regard to time, and a multispot satellite including:a transponder including an amplification device for amplifying signals emitted by the gateway on a forward link and signals emitted by the cells on a return link, and a continuous power supply system of the amplification device, the supply system including means for supplying the amplification device providing the whole of the sub-zones with their respective capacity profile evolving over the given period, the maximum continuous power delivered by the supply system being lower than the continuous power which the amplification device would consume to provide simultaneously the whole of the sub-zones with their maximum capacity value, the N capacity profiles being defined by a curve C i (t) with i varying from 1 to N and t evolving on the given period, the method comprising the following steps: summing the N profiles C i (t) to obtain a global capacity C ⁡ ( t ) = ∑ 1 N ⁢ ⁢ C i ⁡ ( t ) ; determining a maximum value C max of the global capacity profile C(t); determining the maximum continuous power delivered by the supply system, the maximum continuous power being greater than or equal to the continuous power which the amplification device would consume to provide simultaneously the service zone with the maximum value C max .
