Abstract: A terminal (100) for optical communication by laser signals including a matrix image sensor used as a tracking and acquisition detector (2). The matrix image sensor is used simultaneously to check that a portion of the laser signals received by the terminal are injected into an optical fibre (1). A spectral filter element (22) is associated with the matrix image sensor to allow such a combination of functions.

Abstract: A first network probe is associated with a first router and with a first end-point of the first router, and a second network probe is associated with a second router and with a second end-point of the second router. The first network probe periodically injects flag packets in parallel to the traffic of a communication tunnel between the first and second end-points, with each flag packet including timestamp information expressing a time reference for the injection of the flag packet. Information relating to a timing variation in traffic in the communication tunnel is gathered, with the timing variation being measured due to a difference between the timestamp information contained in the flag packets and timestamp information relating to the instant the flag packets were captured by the second probe. Possible congestion situations experienced by the communication tunnel are assessed as a function of the gathered information.

Abstract: A device for the reception of ADS-B messages for a satellite is disclosed including an array of sources and a beamforming module, a ground footprint of a field of view defining a service area, different service areas being associated with different positions of the satellite, a ground footprint of a beam defining a spot in the service area, the beamforming module being configured to form each beam by applying combination coefficients, the reception device having a processing circuit configured to obtain information representative of a position of the satellite and to modify a set of combination coefficients so as to adapt the surface area and/or or the shape of the formed spots to a geographical distribution of the aircrafts within the service area associated with the position of the satellite.

Abstract: A radiator for a geostationary satellite is disclosed having a radiative panel perpendicular to a radiation axis, and pivoting relative to the radiation axis, a mounting foot for the panel, a motor which rotates the mounting foot about a rotation axis, the radiation axis and the rotation axis being tilted relative to each other by an angle corresponding to the angle of the satellite's orbital plane relative to the ecliptic plane of the planet, and a guidance system for the panel, limiting rotation of the panel about the rotation axis, including a connecting arm pivoting relative to the satellite about a first axis and relative to the panel about a second axis concurrent with the first axis at a point of intersection of all the axes.

Abstract: A system for injection of a useful radiation beam into an optical fiber is disclosed including a secondary radiation source, which is connected to the optical fiber such that a secondary radiation beam leaves by an end of the optical fiber. A variable deviation device, for deviating the useful radiation beam towards the end of the optical fiber, an optical detection assembly, identifying the direction of the secondary radiation beam, and an injection controller, for controlling the variable deviation device depending on the direction of the secondary radiation beam. The secondary radiation may be made up by an amplified spontaneous emission from a laser amplifier which is used for amplifying the useful radiation. The injection system may advantageously be used in a terminal for optical telecommunication by laser signals.

Abstract: A heat-insulating multi-layer blanket for a spacecraft is disclosed including a stack of numerous heat-insulating layers, and an external layer superimposed on the stack. The external layer includes a second surface mirror (SSM) film, including a mirror layer placed under a fluorinated ethylene propylene (FEP) layer, and a polyimide layer joined to the SSM film. The blanket has two different configurations depending on the side of the external layer that is exposed to space.

Abstract: A method for securing a geographical area encompassing a route. A map of the area is obtained. A weapon is associated with a firing modeling consisting of a probability model of hitting its target when shooting, as a function of the firing distance. Positions of potential shelters of threats on the map are determined by using a trained artificial intelligence device. The modeling is applied for each weapon and potential shelter while relating the shots to the route and summing all the probabilities of hitting its target on each portion of the route. The potential shelters most likely to constitute attack threats along the route are determined. A path is defined in order to address these potential shelters most likely to constitute attack threats.
