Impact of controlled and semi-controlled re-entry on Spacecraft design

There is increased attention being given to safeguarding Earth's orbital environment, as reflected by the number of relevant regulations that are being set forward by national governments and international organisations. Among others, ESA has published a Space Debris Mitigation Policy for Agency Projects (ESA/ADMIN/IPOL(2014)2), supported by the corresponding ESA Space Debris Mitigation Compliance Verification Guidelines (ESSB-HB-U-002).

Enhancement of Loop Heat Pipe (LHP) Modelling Tool
The current Loop Heat Pipe (LHP) module is increasingly needed to support thermal control design and modelling activities for various missions such as Aeolus, MTG and ExoMars. It is fully operational but only for a limited number of LHP architectures and analytical scenarios and they do not cover current needs. The proposed activity aims to further develop and extend this module the following ways:
  • Tuning of the module to improve performance and steady state convergence.

    Generic AOCS/GNC techniques and design framework for Failure Detection Isolation and Recovery
    The activity will include the following tasks:
     
    • Critical analysis of customer's requirements evolution between fully segregated HW constraints for Safe Mode (traditional ESA approach)and authorised reusepending justifications.
     
    • Critical analysis of current AOCS/GNC FDIR complexity and proposals for simplification with equivalent coverage, including model-based approach orintelligent sensors.

      High-Altitude pseudo-satellites for telecommunication and complementary space applications

      The interest in HAPS is increasing in many areas, from military and security to commercial services. On the telecommunications side, HAPS are seen as relays to provide internet services worldwide, and as a possible complement to satellites. On the Earth observation side, the near-space location of the HAPS enables new services or could improve the existing satellite ones. From the satellite or from the HAPS market sides, it is important to understand how both systems can offer complementary services, and what the possible synergies between them are.
