Abstract: A VHTS or HTS multibeam telecommunications payload includes a first multibeam antenna system with passive antennas, which is configured to receive from and transmit to spots of access stations GW respectively in a first satellite receive Rx band and a first satellite transmit Tx band, and a second multibeam antenna system with passive antennas, which is configured to receive from and transmit to a user coverage zone respectively in a second satellite receive Rx band and a second satellite transmit Tx band, by generating multiple satellite receive user spots and multiple satellite transmit user spots. The payload is wherein it comprises a digital core, based on a digital transparent processor DTP offering total connectivity and total flexibility of allocation of frequency slots to the access station and user spots, and associated with the DTP an RF switching set, made up of one or more matrices of RF switches on source accesses of user spots in satellite transmit Tx only or in satellite transmit Tx and in satellite receive Rx so as to implement operation by beam hopping on clusters Gj/G′j of Tx and/or Rx user spots for which the number of spots Rj/R′j is less than or equal to the total number P of access station spots.

Abstract: A multibeam satellite radiocommunications system includes at least one satellite having at least one passive multibeam antenna system, at least one satellite terminal, a resource allocator configured to form a regular network of satellite spots arranged according to a mesh in quadrilateral form over a given geographic zone, to associate spectral resources with the satellite spots, then to allocate spectral resources to the satellite terminals as a function of their position, wherein the resource allocator is configured to, in the event of failure of a satellite spot, extend the zone of coverage of the satellite spots adjacent to the failing satellite spot so as to cover the surface that it occupies, and allocate new spectral resources to the satellite terminals of the failing satellite spot as a function of their position. A resource allocator and the corresponding method are also provided.

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 distributed amplification device with p inputs, p outputs, p amplification paths comprises a redundant reservoir of n amplifiers including n-p back-up amplifiers, an input redundancy ring and an output redundancy ring formed by rotary switches, the input and output redundancy rings sharing the same technology. The internal amplification pathways associated with the n-p back-up amplifiers frame in an interlaced manner the internal amplification pathways associated with the p nominal amplifiers and the amplification paths of the routing configurations each pass through at least five rotary switches. The input and output redundancy rings are topologically and geometrically configured and the family of the routing configurations is chosen such that the electrical lengths of all the paths of one and the same routing configuration of the family are equal.
