Method and system for estimating attenuations of the respective uplinks of nominal satellite access station(s) to a vhts very high throughput telecommunications satellite

A method for estimating, at one and the same given time, a set of attenuations of one or more first very high throughput radiofrequency RF telecommunications uplinks connecting one or more first nominal satellite access stations to one and the same VHTS very high throughput telecommunications satellite,

• the method for estimating the set of one or more attenuations of the one or more first radiofrequency RF uplinks being implemented by a VHTS space telecommunications system comprising:
• a VHTS very high throughput telecommunications satellite;
• a predetermined whole number N, greater than or equal to 1, of first nominal satellite access stations GWn(i) (6), i being a first index varying from 1 to N;
• and
• a predetermined number P, greater than or equal to 1, of second diversity satellite access stations GWp(j), j being a second index varying from 1 to P;
• and
• a plurality of user terminals, and a space telecommunications system control and coordination station, configured so as to manage diversity,
• each first nominal satellite access station GWn(i) having a first very high throughput traffic uplink LUn(i) operating in an uplink transmission band and, in association, a first very high throughput traffic downlink LDn(i) operating in the Q band;
• and
• the VHTS space telecommunications satellite comprising a payload having:
• an antenna system for generating reception and transmission satellite spots associated with the one or more first and second access stations and transmission and reception spots associated with the user terminals, and
• a regenerative or digital transparent processor DTP, configured primarily so as to provide high-degree connectivity and high-degree flexibility for the allocation of frequency slots to the reception and transmission satellite spots for the first and second access stations and to the transmission and reception satellite spots for the user terminals,
• the method for estimating the set of attenuations being comprising:
• characterized in that it comprises:
• an auxiliary step of using the digital transparent processor DTP, wherein:
• the digital processor generates a common beacon signal or a plurality of different beacon signals and distributes it/them, via a number S of transmission satellite spots in the Q band, greater than or equal to 1 and less than or equal to N, to the N one or more first radiofrequency RF downlinks LDn(i), i varying from 1 to N, in order to be measured in terms of power, or the digital processor measures, for each first uplink LUn(i), i varying from 1 to N, a spectral power of the very high throughput traffic signal received by the satellite corresponding to the traffic signal transmitted by the corresponding first nominal satellite access station GWn(i);
• and
• a following step of determining the attenuation levels An(i) of the uplinks, i varying from 1 to N, based on the powers of the beacon signal or signals measured by the one or more first nominal access stations GWn(i), or based on the one or more spectral powers, measured by the digital processor, of the traffic signals received by the satellite and transmitted by the one or more first nominal access stations GWn(i).
