Marine Litter Aggregation Forecast

Marine Litter Aggregation Forecast presents a new estimation of long-term global distribution of marine litter proceeding from land-based and from sea-based sources at global scale, taking advantage of numerical reanalysis databases of historical met-ocean conditions. Different machine learning techniques are applied to generate long-term climate-based series of those environmental variables that may affect the drift of marine litter over the sea surface such as currents, wind and wave-induced Stokes drift.

Design for Recycling - Mission architectures to manufacture, refurbish and recycle satellites on-orbit

The main objective of the OMAR Mission Architecture study is to identify and trade-off different mission architectures, to provide different services on-orbit. For each of the relevant scenarios, this objective shall be achieved by defining the associated system functional analysis and by trading-off different architectures and concepts of operations. Furthermore, the impact of aspects such as: operational orbit, type of serviced satellites, services provided, different levels of autonomy, and any other relevant factors is to be assessed.

Harmonising MBSE standards into ECSS – Model-Based System Engineering – Study Scheme

ESA has traditionally specified space systems using a document-based approach, and is now in a transition process towards the digitalisation of systems engineering activities. At the same time, space industry companies have their own internal set of best practices and experience with Model-Based Systems Engineering (MBSE).

To solve this problem, ESA initiated this study led by CGI in partnership with OHB to identify a way to harmonise the different MBSE approaches from industry and compile the information into a concise book.

Small Satellite Missions to Mars – S2M2

The activity 'Small Satellite Missions to Mars (S2M2)' is an early-phase architecture study of a potential low-cost mission to Mars as further step in the Mars exploration roadmap developed by ESA.

A potential implementation from industry’s point of view was assessed, applying the strict design-to-cost philosophy by fostering strong reuse of an available OHB platform. Trade-offs were performed for assessing a low-cost mission profile targeting the programmatic constraints that were input to this study.

Analysis of space debris recycling potential to supply raw materials for construction on the Moon

As on Earth, space debris should not only be seen as a threat. Instead, the value of waste as a recycled good should be understood. On Earth, this potential is already fully recognised. The German recycling industry alone generates more revenue than the entire European space industry. Nevertheless, this treasure was never lifted in space.

Development of a Compliant Mechanism Based on Additive Manufacturing
Compliant mechanisms (e.g. flexural joints) are applied where the relative motion of parts can be accomplished without using traditional bearings. Slender structures can be properly arranged to provide functions like accurate guiding, speed reduction, or change of motion direction. Compared to traditional mechanisms using bearings, significant improvements are expected. These include a decrease of part count number, frictionless motion transmission, which decreases losses, higher motion ranges, enhanced stiffness, and improved accuracy due to the avoidance of backlash.

Advanced Processing Techniques for Next Generation Multi-channel SARs

Over the last decades, the spaceborne remote sensing community has been focused on the development of imaging radars at RF frequencies such as S-band, L-band, C-band and X-band.


ITU regulations currently permit the use of Ka-band for active spaceborne microwave remote sensing but only few missions are considering applying this frequency band such as the SARAL mission with the ALtiKa instrument (launched 2013).
