  • Patent number: 9118384
    Abstract: A payload includes one or more antennas for receiving polarized radiofrequency signals; a device for regenerating radiofrequency signals by filtering, frequency transposition, and amplification; and antennas for transmitting the regenerated radiofrequency signals to one or more terrestrial terminals. The radiofrequency signal regeneration device includes a plurality of regeneration channels, each channel consisting of an amplification device capable of amplifying two radiofrequency signals having separate frequency bands and the transmission antennas associated with a regeneration chain are capable of transmitting two regenerated radiofrequency signals having orthogonal polarization directions and intended for cells belonging to a single cell layout that uses at least two separate frequency bands and two separate polarizations.

  • Patent number: 8594661
    Abstract: A method for establishing radiofrequency links via a telecommunication satellite having several spots, designated a multispot satellite, between at least one terrestrial station and a service area composed of a plurality of elementary covering zones, designated cells, each cell comprising a plurality of terrestrial terminals is disclosed. This type of satellite allows the use of several spots of antennae on board the satellite to cover contiguous geographical zones or cells, instead of a single broad spot. Each cell is associated with a spot to which a frequency band is attributed. In the case of the loss of a spot associated with a cell, designated a faulty cell, the spot (FR1, FR2, FB1, FB2, FV1, FV2) associated with at least one contiguous cell (CR1, CR2, CB1, CB2, CV1, CV2) to the said faulty cell is likewise associated with a part of the said faulty cell so that the area (CPJ?) of said faulty cell is reduced.

  • Patent number: 8149869
    Abstract: The present invention relates to a telecommunication network for establishing radiofrequency links between gateways and ground terminals via a telecommunication satellite with several spot beams, known as a multispot satellite. The network includes a multispot satellite including a payload for the reception, processing and retransmitting of telecommunication signals received by said satellite, a service area comprised of a plurality of basic coverage areas, known as cells, each cell including a plurality of ground terminals and a plurality NGWactive of active gateways interconnected by a ground network, NGWactive being an integer, said satellite relaying signals sent by said NGWactive active gateways to said cells. Furthermore, the network includes NGW gateways, NGW being an integer strictly greater than the number NGWactive of active gateways, said NGW gateways being interconnected by said ground network and including said NGWactive active gateways such that NGW?NGWactive gateways are not active.
