Abstract: A method for estimating, at one and the same given time, a set of attenuations of one or more first radiofrequency RF uplinks, implemented by a VHTS space telecommunications system. In an auxiliary usage step, an on-board regenerative or digital transparent processor DTP generates at least one beacon signal that is or are distributed, in the Q band, to N nominal access stations GWn(i) in order to be measured in terms of power, or measures the spectral power of each traffic signal transmitted by the nominal access stations GWn(i), i varying from 1 to N. In a following step, the attenuation levels An(i) of the uplinks LUn(i) are determined based on the powers of the one or more beacon signals that are measured on the corresponding downlinks LDn(i) in the Q band, or based on the one or more spectral powers, measured by the DTP, of the traffic signals received on the one or more uplinks LUn(i).

Abstract: A method for managing the telecommunication data traffic of a very high throughput satellite communication system wherein, for each satellite, the management of a so-called n+p site diversity and/or of a load diversity is implemented in a digital transparent processor in the satellite to guarantee the availability of the very high throughput communication system.
