Test methodology investigations and parameters influencing Passive InterModulation (PIM) interference

Passive intermodulation is a real threat to all types of payloads. In some cases, it could even lead to total lost of the spaceship. Despite of this, there is very weak understanding of the parameters that generate this unwanted interference as well as their influence in the amplitude of the interfering signal. In addition, there is a total lack of agreed testing techniques, procedures and methodologies as well as justified test margins, as has already been recently stated by the European community (National Delegations, satellite operators and Eurospace).

AOCS COTS hardware fostering AOCS architecture and functions innovation
The use of equipment based on COTS for small/constellation/low-cost platforms is impacting the reliability, availability, performance and robustness of the commonly used AOCS [Attitude and Orbit Control System] equipment (e.g. Gyros, star trackers, GNSS receivers). This activity explores innovative solutions at AOCS functions and architecture level (incl. AOCS FDIR) to mitigate the changes introduced by the use of COTS hardware for AOCS equipment.

Fast development of kinetic impactor for short-warning asteroid deflection

The study demonstrates that in an emergency situation, with only a very short warning time, the launch of a fast asteroid kinetic deflection mission is feasible (targeting launch-readiness in six months!), given that certain identified pre-requisites have been prepared well in advance. The capabilities and requirements of 'hijacking' and modifying a commercial spacecraft platform in order to perform asteroid kinetic deflection in the shortest possible time were consequently assessed.

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.

    End of Life operations for disposal of mega‐constellations

    The objective of this activity was to understand the operational complexity of large mega-constellation systems, and the potential needs to operate these, including the complexity of collision avoidance manoeuvres (CAMs). This objective was achieved by:

    Membrane Gas-Water Separation - Membrane Condensing Heat Exchanger (MCHX) Technology Demonstrator

    Manned missions into space require systems for Environmental Control and Life Support (ECLS). The major tasks of these systems are the control of the habitable volume atmosphere in which the astronauts shall feel themselves comfortable. Essential functions are to control cabin temperature and humidity. For these functions a Membrane-based Condensing Heat Exchanger (MCHX) Technology Demonstrator was developed and performance tested.
