Focal plane assemblies for earth observation missions require cooling around 77K to 120K. The cooling is provided by radiators or redounded active coolers (e.g. Stirling or Pulse Tube Coolers). In most cases the component temperature should be stabilized in order to achieve the best performance. In addition, the detectors have to be mechanically decoupled from the rest of the structure and the cooling source to avoid thermo-elastic distortions and disturbances caused by micro vibrations e.g. from active coolers or reaction wheels.

After the successful evaluation campaign of the component, Faint Star is now used by a number of designs (Star Trackers and Navigation Cameras). The guarantee of supply is vital for the space industry. Following a company?s decision to stop commercialising the component, the proposed contractor is taking over. The manufacturing chain is not affected by this transfer. The design of the component is unchanged for the silicon die (produced at the same foundry), the package and its assembly.

Given the unstoppable trend towards more software-driven (defined) system components as well as system safety and security awareness, dependence on on-board SW platform for mission safety and security will become critical.
 
A new development to enhance the security of low-cost software platform solutions is considered essential. Requirements like dependability, scalability, obsolescence and re-usability shall be taken into account as well.
 
The intended work includes the following tasks:

    A PCM provides a temporary cooling capability of electronics boxes when overheating/absence of effective cooling leads to over-temperature for any type of spacecraft or launcher. The proposed technology saves mass vs traditional heat sinks for applications where high power dissipation occur for a short period of time.
    The activity shall focus on the following points: ?
     
    • Radiation resistance of organic PCM?s: samples and whole PCM box, needing a large quantity of PCM to be irradiated under p and gamma

      This de-risk activity has successfully demonstrated that the use of the component level length scales over compound length scales in the calculation of heating rates can lead to a significant over-prediction in component temperatures.

      The scenario of satellite-based products is wide and heterogeneous: it includes a large variety of Earth sciences data collected by heritage missions, Earth Explorer and operational missions, as well as future missions. At the same time the scenario of potential users is evolving: multi-disciplinary systems (e.g.

      The concept of digital twins in industry relates to the development of data models for physical systems to accurately reproduce physical and performance characteristics of processes and products. It is often referred to as a virtual replica of the physical asset which can be used to monitor and evaluate its performance. In the scope of Industry 4.0, the digitalization of manufacturing processes bring significant potential in the improvement, namely in lowering manufacturing costs, improving performances, increasing reliability, and in reducing the time to market.

      Control Moment Gyroscopes (CMGs) of compact size target the small satellite market, especially for agile attitude control of satellites with high-resolution optical instruments. With the ability to acquire high-resolution images, the swath width is typically limited by the narrow field of view of the instrument’s optics. In order to enlarge the field of view, an agile attitude control system is advantageous because the ground target area can be substantially expanded by pointing the entire satellite.
