Flexible payload architecture for VHTS and HTS applications
First Claim
1. A multibeam telecommunications payload for applications of very-high-throughput space telecommunications or of high-throughput space telecommunications comprising:
- a first multibeam antenna system of passive antennas, which is configured to receive from satellite receive Rx access station GW spots and transmit to satellite transmit Tx access station GW spots, respectively in a first satellite receive Rx band and a first satellite transmit Tx band; and
a second multibeam antenna system of 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 being wherein it comprises;
a digital core, based on a digital transparent processor DTP, dimensioned through a sufficient number of accesses at input and at output to be connected to all the spots of the access stations and all the user spots, and configured to offer total connectivity and total flexibility of allocation of frequency slots to the access station and user spots; and
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 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.
