Data compression as a service

The Data Compression as a Service (DCaaS) study aims to bring the benefits of data compression to the experimenters on ESA's OPS-SAT platform. It focuses on using the POCKET+ algorithm for the compression of housekeeping telemetry data. The project contains a space component, which performs the compression of provided user data, and a ground component, for the decompression of transmitted user data. Three use cases were selected within the scope of the project: file-to-file, packet-to-packet, and stream-to-stream lossless data transfers.

MoBaTe – Enabling Model-Based Testing and Automated Test Case Generation for Ground Segment Data Systems

The driver behind the MoBaTe activity was to propose ways to improve the current software development and validation lifecycle using MBSE techniques to shift some of the system validation activities to the early stages of development. The roadmap to achieve this included identifying strategies, required model properties, modelling tools and languages needed to move from a requirements-based approach to a model-based approach. All this considering existing and established workflows and tools currently used by ESA.

SaasyML: Onboard Machine Learning Software As A Service For Experimenters

The “SaaSy ML” idea will provide experimenters with on-board Machine Learning (ML) functionalities that any app can subscribe to via a Software as a Service (SaaS) app hosted on the Satellite Experimental Processing Platform (SEPP). The ML features provided by the SaaS app will cover both training and prediction operations. The JSAT open-source java library for ML will be re-used thus making accessible over 100 training algorithms on-board a flying mission. Re-using the JSAT library will ensure the development to focus on the idea's novel aspect: a spacecraft SaaS app for in-orbit ML.

Fused Layer Deposition of Lunar Regolith

In order to enable lunar exploration in a sustainable manner, it is necessary to develop technologies that allow the use of lunar resources in-situ. Additive manufacturing techniques are being studied for in-situ resources utilization on the Moon (e.g.: solar or laser sintering). The results of these studies, presented samples with low mechanical properties due to the formation of defects and cracks within the final product.

Additive Manufacturing of pure copper electromagnetic coils
In space, copper coils are used for attitude control of satellites which are called magnetic torquer if a core material is used. The winding of the copper coils of magnetic torquer is a time consuming process, which is difficult to automate, especially because each coil is optimized for a given mission. Consequently, additive manufacturing has high potential to minimize the production time in the future, as well as to optimize winding shapes.

De-risk assessment: Additive manufacturing of soft magnetic material for satellite actuators - AMMMSA

The goals to improve mechanical and magnetic material properties for soft magnetic Ni50Fe50 specimens processed by LPBF was achieved. Tensile strength is with ~500 MPa higher than the targeted 365 MPa and close to values of conventionally processed material. Whereas, magnetic properties measured are still lower than those specified in the datasheet of PERMENORM 5000V5 material by VAC. Since the density achieved is already close to 100% it can be concluded that not only density has a strong influence on the magnetic properties.

MBSE enhanced by Semantic DataLake integration and Machine Learning

The Integrated MBSE Analytics Platform (IMAP) has been developed in the course of the OSIP [OSIP] MBSE campaign’s MBSE2DataLake project. It demonstrates how MBSE data can be downstreamed from early phases and integrated with Telemetry data or system operations data. Applying MachineLearning analytics and customized visualization on these sets of integrated data provides seamless analysis capabilities and data browsing experience for the user. The approach leads to linking the former separated domains of System Design and AIT/Operations.

Moon Fibres

Institut für Textiltechnik der RWTH Aachen University (ITA) and Institute for Structural Mechanics and Lightweight Design RWTH Aachen University (SLA) have already spun MoonFibres from regolith simulant. Gradel SARL uses the xFKin3D technological process to produces ultra-lightweight structural components made of various types of fibres and resin. This technology requires less material to create parts with equal structural strength as the ones produced in traditional ways. The produced parts can be 2D or 3D parts.
