METHOD AND SYSTEM FOR ESTIMATING ATTENUATIONS OF THE RESPECTIVE UPLINKS OF NOMINAL SATELLITE ACCESS STATION(S) TO A VHTS VERY HIGH THROUGHPUT TELECOMMUNICATIONS SATELLITE

摘要

A method for estimating, at a same given time, a set of attenuations of one or more first radio frequency RF uplinks, implemented by a VHTS space telecommunication system. In an auxiliary operating step (304), an on-board digital transparent processing DTP or regenerative processor generates at least one beacon signal, distributed in Q band to N nominal access stations GWn(i) in order for the power thereof to be measured, 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 consecutive step (306), the attenuation levels An(i) of the uplinks LUn(i) are determined from the powers of the beacon signal or signals measured on the corresponding downlinks LDn(i) in Q band, or from the spectral power or powers measured by the DTP of traffic signals received on the uplink or uplinks LUn(i).
