Abstract: An intermediate network for a radiocommunication system, the intermediate network includes one or more stations located on high-altitude platforms in order to connect a set of remote base stations to one or more ground stations. The high-altitude platforms are networked by way of communication links, for example high-speed free-space optical links. The invention also proposes to connect remote base stations positioned outside of the area of coverage of the stations located on high-altitude platforms via for example microwave-link relay stations or base stations at the edge of the area of coverage.

Abstract: A satellite-based very-high-throughput system is provided and a web-caching system based on a high-altitude platform station, an aerostat for example, having the advantage of decreasing the throughput required over the feeder link without however requiring a cache server to be installed on board the satellite.

Abstract: A station placed on a high-altitude stationary platform includes two main emitter/receiver sets, each configured to establish a main communication link with a remote terminal station or with another station placed on a high-altitude stationary platform and two backup emitter/receiver sets, each configured to establish a backup communication link with a repeater placed on a relay station on the ground or at sea or with a remote terminal station, the station furthermore comprising a control facility configured to selectively activate a main communication link or a backup communication link as a function of an indicator of the operating state of the main communication link.

Abstract: A method for transparent on-board routing of data packets at high bit rate is implemented by a telecommunication system comprising an origin transmitting station, a first destination receiving station, a second destination receiving station, and a plurality of at least two satellites. The origin transmitting station segments high bit rate data streams into coded or uncoded packets each having the structure of a coded or uncoded DVB-S2 baseband frame BBFRAME; and the origin transmitting station inserts, for each segmented BBFRAME packet, coded or uncoded, an on-board routing label of a single piece respectively associated with the coded or uncoded BBFRAME packet. The on-board routing label contains an identifier of the destination receiving station associated with the coded BBFRAME packet, out of the first destination receiving station and the second destination receiving station.

Abstract: A transmitter of a binary data stream comprises: a serial/parallel converter to split the binary data stream into m different parallel bit streams, each bit stream having a rate D/m which is m times lower than the initial rate D; m first encoding modules to error-correcting encode each bit stream individually; a time-interleaver to intermix the information bits originating from different encoded bit streams; an encoder to error-correcting encode the m interleaved bit streams into p bit streams; p electro-optical modulators to modulate each of the p bit streams delivered by the interleaver by means of p optical carriers of different wavelengths; and a wavelength-division multiplexer to combine the less p optical carriers into a single optical signal.

Abstract: A satellite telecommunications system has a global coverage area and a plurality of user terminals distributed in the global coverage area. The global coverage area is covered by a first set of spots which form a regular cellular mesh, and by at least a second set of local spots, irregularly distributed and superimposed geographically on spots of the first set. The spots of the first set of spots have allocated channels with the same frequency capacity, the same channel being re-used by a plurality of different spots, and the local spots of the second set of spots have a special allocated channel having an increased frequency capacity.
