| 摘要 |
The present invention concerns a telecommunication network for establishing radiofrequency links between at least one gateway and ground terminals via a multispot telecommunication satellite. The network includes a service zone composed of a plurality of cells each including a plurality of ground terminals, the said 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 said maximum values of each of the capacities being shifted with regard to time and a multispot satellite including a transponder including amplification of the signals emitted by the gateway on the forward link and the signals emitted by the cells on the return link and a continuous power supply system of the amplifier. The said supply system includes means for supplying the amplifier providing the whole of the sub-zones with their respective capacity profile evolving over the said given period, the maximum continuous power delivered by the supply system being less than the continuous power which the amplifier would consume to provide simultaneously the whole of the sub-zones with their maximum capacity value.
