Abstract: A Fourier-transform interferometer with self-apodization compensation comprises at least one pair of mobile prisms forming a plate with thickness which varies at the same time as an optical path length difference is itself varied. The prisms are displaced using a mobile system with a single degree of freedom, comprising two support elements and at least two rotatably hinged levers. The interferometer is adapted to be installed on board a satellite, for spectral analysis of a radiation originating from the Earth's surface.

Abstract: A method (50) for detecting broadcast signals, transmitted by terrestrial sources (40) and received by a satellite (20), in individual signals obtained respectively from different individual antennas (24) of an antenna array (22) of the satellite, includes a first detection iteration (51a) and a second detection iteration (51b), each of the first and second detection iterations including a step (52) of forming, from the individual signals, virtual beams of different respective main radiation directions, and a step of searching for the presence of broadcast signals in the virtual beams. Furthermore, for at least one broadcast signal detected during the first detection iteration, the respective contributions of the at least one detected broadcast signal to the different individual signals are attenuated, relative to the first detection iteration, for all or part of the virtual beams formed during the second detection iteration. A system (10) for detecting broadcast signals is also described.

Abstract: An aircraft having propulsion units for both conventional aircraft flight in the atmosphere and for high-altitude operation as a rocket. The aircraft is divided into a payload compartment and a compartment containing rocket propulsion unit propellant or fuel, and includes a long transverse wing with a small back-sweep to favour lift in the dense layers of the atmosphere and to thus make it possible to climb to high altitudes at a subsonic speed before using the rocket propulsion units. The return flight portion is performed by gliding or controlled as for a conventional aircraft.

Abstract: A method and system for estimating a path-length difference between two paths followed by a target signal transmitted by a spacecraft or aircraft to a first receiving antenna and a second receiving antenna of a receiving base, respectively. A useful-phase difference is measured between signals that correspond to the target signal received by the first receiving antenna and second receiving antenna. The path-length difference is estimated in accordance with the useful-phase difference measurements. The measurement of the useful-phase difference comprises either correlating the signals received by the first receiving antenna and second receiving antenna, respectively, with a reference target signal, or analyzing the signals received by the first receiving antenna and second receiving antenna, respectively, using an FFT or a PLL.

Abstract: A method and telecommunications system for identifying uplink multiplexing resources of a multi-beam satellite that are usable in a land-based telecommunications system, e.g., a transmitting station for transmitting radio signals to a receiving station. The transmitting station or the receiving station being a base station having a range defining a coverage area. For a given uplink multiplexing resource, a maximum allowable interference level, with respect to the satellite, for radio-electric signals transmitted from the coverage area is estimated. A potential interference level of the transmitting station is estimated. The transmitting station determines the usability of the given uplink multiplexing resource by comparing the potential interference level with the maximum allowed interference level for the given uplink multiplexing resource.

Abstract: A method for stabilizing a line of sight of an imaging system on board a satellite uses windows selected within an image sensor. Variations of the line of sight can be characterized at a frequency that is greater than that of a sequential mode of image acquisition by the sensor. The stabilization method can be implemented at the same time as the full-frame acquisition of images by means of the imaging system.
