    OPTICAL COMMUNICATIONS / LASER LINKS

    Data transmission via laser links offers higher throughput & security than radio-frequency. A laser link terminal is made of 4 building blocks including a laser modem, a fine pointing device, a beam expanding telescope & a coarse pointing gimbal, and connects satellites to the ground (feeder links) or to other satellites within a constellation.

     
    FINE POINTING DEVICE

    [Under development]

    An optical sensor is used to track the received beams and actuate a fine steering mirror to optimize the transmission. Sodern leveraged its heritage with piezo mechanisms and optronic detection to develop this device.

     
    COARSE POINTING GIMBAL

    [Under development]

    Its function is to point the larger beam on the other terminal according to its coarse position. The gimbal has two axes of rotation in order to be able to reach any other satellites.

    Gimbal Datasheet
     
    BEAM EXPANDER TELESCOPE

    [Under development]

    The function of the telescope is to expand the diameter of the laser. A laser beam means that the laser energy is more concentrated by the emitting terminals, and more energy is collected by the receiving terminals. The telescope is manufactured thanks to advanced mirrors fabrication technologies and innovative integration methods.

  • High data transmission
  • No interference
  • Compact design

  • Telescope Datasheet
     

    MODULAR PAYLOADS

    OPTICAL SWITCH

    [Under development]

    The switch matrix is an innovative solution to manage photonic signals in a communication payload. The switch enables remote interconnection of a large number of fiber channels (up to 96 x 96) with very low insertion loss thereby providing a high degree of flexibility to the payload architecture.

    SCIENTIFIC & SYSTEM EXPLORATION INSTRUMENTS

    A few examples

    EUROPA CLIPPER

    JPL/NASA selected Sodern in early 2018 to supply the star tracker of the future Europa Clipper mission. Sodern thus accepted the challenge of developing a new star tracker, derived from our product Hydra, but specifically dedicated to Jupiter’s harsh environment: the most radiative in the entire solar system. The mission aims at studying Jupiter’s atmosphere and its magnetosphere; and characterizing the composition and physical properties of Europa, Ganymede and Callisto. To sustain Jupiter’s harsh environment, shielding has been added around the star tracker, radiation-resistant electrical components have been selected or developed, and a high-performance software derived from Sodern’s traditional star trackers software has been designed.

     
    JUICE

    The European Space Agency selected Soden to supply a Navigation camera (NavCam) for the JUpiter ICy moons Explorer (JUICE) mission. The NavCam serves both navigation and science purposes. Faced with Jupiter’s Moons’ hostile, radioactive environment, this set of instruments has required intensive software and hardware developments to provide the mission with reliable guidance and navigation systems.
