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.

HOPAS (Hybrid online policy adaptations strategy) on OPS-SAT

While AI technologies have shown promise in various applications in the space industry, their adoption within spacecraft flight software has yet to happen in a significant manner. This is due to a number of factors, including the relatively low computing power available onboard traditional spacecraft, the long development process required in the industry and the lack of opportunities for in-orbit demonstrations. In ESA's OPS-SAT satellite, Airbus teams identified a unique opportunity to quickly test promising algorithms in orbit as the industry seeks to resolve the issues listed above.

MBSE Deployment for EnVision Science Mission Study

Following on from the successful Venus Express mission (2006 – 2014), the EnVision mission is a mission to observe the surface of Venus at an unprecedented resolution, investigating signs of active geology and looking for evidence of the past existence of oceans. EnVision is meant to help in the understanding of why this most Earth-like planet has turned out so differently and open a new era in the exploration of our closest neighbour. EnVision is proposed as a joint mission with NASA, with payload elements funded by the ESA Member States.

Preliminary design of on-orbit manufacturing of large antenna reflectors

This study aims to carry out the conceptual design of a large-parabolic-antenna reflector that is manufactured and assembled on-orbit.

Through its Clean Space initiative, ESA has been devoting an increasing amount of attention to the environmental impact of its activities, including its own operations as well as operations performed by European industry in the frame of ESA programmes. In its Technology Strategy, ESA identified 'Inverting Europe’s contribution to space debris by 2030' as one of the four technology development targets.

Securing NG-Ultra FPGA development through innovative System-on-a-Chip (SoC) validation
The BRAVE series of reprogrammable FPGA’s represent an entirely new area of development for microelectronics. These high performance, very advanced electronics could revolutionise the manufacturing process and performance of multiple missions. Alongside their development there is a current industry initiative to standardise avionics systems. As part of this venture, GSTP Element 2 has initiated an activity to develop a standardised box, which will contain all the different computer modules, such as power boards, and ensure they are all compatible.

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.
