20090051588 | DEVICE FOR TRANSMITTING AND/OR RECEIVING SIGNALS WITH FREQUENCY RE-USE BY ASSIGNMENT OF A CELL FOR EACH TERMINAL, FOR A COMMUNICATION SATELLITE - A device (D) is dedicated to transmitting and/or receiving signals representative of data in a communication satellite (SAT) having a fixed frequency bandwidth. This device (D) comprises transmission and/or reception means (MER) responsible for sending and/or receiving signals in multiple beams, and control means (MC) responsible for defining a chosen number of cells of chosen dimensions and positions, and configuring the transmission and/or reception means (MER) so as to define beams each associated with at least one of the defined cells, with a chosen carrier frequency based on the requirements of each of the cells and taking into account the frequency bandwidth available on the satellite (SAT). | 02-26-2009 |
20110267229 | Distributed Distance Measurement System for Locating a Geostationary Satellite - A distance measurement system for locating a geostationary satellite equipped with a transponder includes: a central station emitting a distance measurement signal; and at least one measurement station receiving the emitted signal, including means for measuring the time of arrival of the emitted signal, and transmitted via the transponder of the satellite. The central and measurement stations, of known positions, include synchronization means with a common time base. The transponder is that of a satellite telecommunications system, and has a bandwidth B. The central station includes means for emitting a specific distance measurement signal, distinct from the telecommunications signals transmitted via the transponder, with periodic events and with spread spectrum, the bandwidth of which is included in B. | 11-03-2011 |
20120154532 | TRANSMISSION METHOD AND SYSTEM USING AN ADAPTIVE AND PROGRAMMABLE HIERARCHICAL MODULATION - A method for transmission of a signal simultaneously including a first stream of binary data and one or more other streams of binary data, the method including, in the following order: dynamic distribution of bits of the data streams between coders, with one coder per data stream; coding the distributed bits using the coders; dynamic distribution of the coded bits between hierarchical levels of a modulator; and hierarchical modulation using the modulator. | 06-21-2012 |
20140112241 | SATELLITE TELECOMMUNICATIONS SYSTEM FOR PROVIDING STAR TRAFFIC AND MESH TRAFFIC - 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. | 04-24-2014 |

20080252514 | Device for Semi-Transparent Multiplexing of Data Stream for a Communicaton Satellite - A device (D) is dedicated to data stream processing within a communication satellite of a communication network. This device (D) comprises processing means (MT) whose job is, in the event of receipt of a first incoming data stream whose carrier exhibits a first modulation and comprising at chosen locations chosen insertion blocks, i) to detect the insertion blocks and at least one characteristic of the carrier of the first incoming stream, chosen from among its frequency, its phase, its timing and its amplitude, ii) to modulate, in accordance with the first modulation and having regard to each detected characteristic, data packets to be transmitted to a destination common with that of the first incoming stream, and iii) to replace with the modulated packets certain at least of the insertion blocks detected in the first incoming stream which has not been demodulated, so that the resulting stream is transmitted by the satellite, with its first original modulation, to the common destination so as to be demodulated therein as if it had been constituted by a single modulator. | 10-16-2008 |
