Due to the ongoing miniaturisation and increased performance of electronics devices, alternative cooling methods are required, specifically mechanical pumping loops (MPL). Passive two-phase loops are not capable of cooling ESA's expected power densities up to 300 W/m2, so pumped two-phase loops are forecasted to replace their passive counterparts. According to Lapensée et al., “the most important component of a MPL is the pump and a pump failure directly results in MPL system failure, a reliable pump is therefore of vital importance".

Today’s satellites are inherently inflexible and purpose-built for a single mission. In contrast, the community is exploring disruptive approaches towards in-orbit reconfiguration and on-board data processing. One of the most promising approaches is to use COTS components and open source frameworks, which decrease time-to-market and could even increase the pool of developers/users on the satellite.

We aim to develop a novel control theory methodology using input-output process models for error mitigation in signal processing data-paths that operate in radiation prone environments. In this approach, difference equations are used to characterize the process with perturbation corresponding to faulty digital circuits.

Tables and graphs are knowingly used to organise data within a company with different levels of depth and complexity. Knowledge graphs (KGs) are particularly useful because they can cope with data diversity (high-quality complete data and sparse and incomplete data), they have a high degree of scalability and flexibility (the semantic data model can be inter-operational, large, wide and as deep as needed) and, last but not least, they provide reasoning and inference capabilities.

Light-trapping helps enhance the light absorption in space solar cells and hence enables their thickness to be reduced to increase the radiation hardness. We have optimised light-trapping structures (LTS) inspired in the diatom frustule and moth’s eyes. As a solar cell reference, we use the commercial 3G30C model from Azure Space Solar Power GmbH. We have developed a physical model to describe the solar cell absorption and derive the efficiency. The optical description relies on the Fourier modal method and the solar cell performance on the detailed balance limit.

The emergence of the classical world from quantum theory, and especially of a consensus among different observers, is a long-standing problem for the foundations of quantum theory. Using recent advances in multipartite quantum information theory, we shed light on these problems. Besides their interest for fundamental physics, they are related to quantum sensing and metrology using a quantum-network of stations, a situation of interest for the potential use of quantum-based measurement probes for exploring space and the Universe.

The main goal of this Ariadna study was to determine the radiation hardness of potential future space processors. The AR0 test-chip was used to study the impact of SEUs and SETs on different versions of a hardened processor on UTBB-FDSOI 28nm technology, including DICE flip-flops, and three different hardening level of combinational logic.

The objective of this activity was to propose a general infrastructure of an end-to-end simulator (E2ES) for space science missions, namely an E2ES requirements baseline, reference architecture and an associated library of software models (building blocks, BB) to promote reuse, standardisation and reduction of engineering costs by defining a products/science validation process throughout the lifecycle based on an E2ES.

The purpose of this study was to define the a communication subsystem architecture (including both ground and space segments, as well as operational methods) that allows robust RF TT&C links during superior solar conjunction phases. The defined architecture shall ensure robust and reliable links in scintillation regimes (i.e. at low SEP angles) where TT&C links are nowadays degraded, leading to occasional link interruptions. Similarly, the defined architecture shall ensure that at even higher scintillation regimes (i.e.
