Satellite communications via space-based internet service providers

In this project, the University of Luxembourg studied and evaluated a new concept of connecting space missions via space internet providers. The system requirements, necessary adaptations, and possible limitations are provided and discussed. Three types of space internet provider were studied and evaluated: Starlink, OneWeb and O3b mPOWER.

Tumbling Motion Assessment for Space Debris Objects
When Europe still had no access to clarify the attitude of lost spacecrafts in order to optimize recovery attempts and improve re-entry predictions, the precursor GSTP study on ?Attitude Motion Measurements and Modelling? activity paved the way for an independent European capacity in this field. In fact, for the first time in Europe, it was possible to join measurements of SLR, passive telescope and synthetic aperture radar to fit a dynamic attitude model of the given spacecraft.

NEU4SST - Neuromorphic Processing for Space Surveillance and Tracking

In this project the authors looked at event-based sensing and processing for space situational awareness (SSA). Many advantages exist with the new paradigm of neuromorphic engineering, the authors investigate whether event-based optical data is suitable for the task and if processing with Spiking Neural Networks (SNN) provides advantages in terms of efficiency and efficacy. With the implementation of a novel heterogeneous LIF SNN, authors claim to surpass the state of the art in event-based SSA with a 15% increase in accuracy.

Modular micropump fluidic systems: For system requiring ultrareliability, high performance and a compact design

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". Wits et al.

Virtual workplace for AIT PA training and operations support
Currently space missions are assembled, tested and verified following manual procedures: for the most part their production, assembly, integration and verification activities are lagging behind the latest ?Industry 4.0? smart factory approaches. Assembly, integration and verification from equipment up to platform and satellite level is a huge set of tasks and the nature of the involved engineering disciplines are very diverse. Activities are performed in parallel at several locations executed by different teams of experts and using a variety of tools.

RESPECT-DEM - Reliable Signal Processing Datapaths Design Using Control Techniques Based on Difference Equation Models

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.

COTS AI accelerators in mixed-criticality high performance avionics for reconfigurable satellites

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.

Advances in Technological Quantum Optics

Commonly used classical cryptographic protocols, such as the RSA-protocol, rely on the hardness of computational problems. With the advent of quantum computing (QC), the hardness assumptions of these problems is nullified, since they can be solved efficiently on a QC. On the other hand, the security of Quantum key distribution (QKD) rests upon the very laws of physics and guarantees information-theoretic security, which not only enables tap-proof communication at present, but also prevents any future technology to crack encrypted messages.
