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: The present invention relates to an in-service reconfigurable antenna reflector comprising a rigid support and a membrane, deformable and having radio-electric reflectivity properties. According to the invention, the reflector comprises a plurality of coupling means connecting the rigid support and the membrane, comprising a first link of finger ball joint type connected to the rigid support, and a second link of finger ball joint type connected to the membrane. Each coupling means furthermore comprises a linear actuator, comprising a rotary motor and a screw-nut assembly, connected to the two links of finger ball joint type, and able to generate, in an operational configuration, a translational motion allowing the deformation of the membrane.
