Space mission integration and testing activities between space and ground segments are today decoupled, based on different simulation facilities in different environments. Indeed, although most elements and building blocks are separately available, currently no coherent environment exists to perform an initial setup at space mission level. A number of technology and organisational solutions need to be achieved (e.g.

This activity analysed the feasibility and performance of the quantum pulse gate (QPG) technique for noise rejection in optical communication systems. The optical frequency band is expected to play an increasingly important role in space communications due to a substantial increase in available data rates with respect to radio transmission, as well as enhanced information security. The main limiting factor for the performance of an optical link is the background noise collected by the receiver, especially when operated at low signal powers, e.g.

While test case definition is test dependent and test performance is human error prone and effort intensive, automated testing proved to be still not reaching a level of abstraction and exhaustiveness to enable significant return on investment.The application of Data Analytics technologies like Machine Learning, Artificial Intelligence or Data Mining to both simulation and test data processing shall provide a level of abstraction and consistency to improve both test automation production and exhaustiveness.

Quantum degenerate gases such as Bose-Einstein Condensates (BECs) are key tools for ultimate precision quantum technologies in space. On earth, gravity prevents long measurement times except in experiments with prohibitively large footprints (10m), however in orbit or in deep space the chilliest terrestrial atomic clouds would take minutes to expand to a radius of 1cm which corresponds to 100km of ballistic free-fall.

The number of RF connector interfaces available for use in the space industry is very limited. The most common and widespread interface is SMA. For high operating frequency, equipment manufacturers typically use the SMA2.4 (up to 50 GHz) and 1.85 (up to 65 GHz). For the last 15 years , Sub Miniature Push-on (SMP) interface has gained a lot of popularity for phased array radars because of its small size and ease of use.

Previous activities (T709-503OS) have looked into the usage of Model based diagnostics at sub-system level (like Thermal) joined with AI for the identification of issues. This work expands to cover the complete system at system level. It uses results from ongoing Digital Twin activities (T708-505SW), but as well standard simulation modelling technology. One key issue to be tackled is the evaluation of the output to reliable detect anomalies.

Satellites have an outer skin of multilayer insulation blankets layer that is needed to control the thermal balance of the spacecraft (S/C).
These blankets need to be fixed to the S/C structure to withstand launch loads and provide the required thermal performance taking into account field-of-views of instruments and other payloads as well as access constraints.

The PhaNi-Neutron project, conducted by the Fraunhofer Institute for Material and Beam Technology IWS,
focused on the phase and strain monitoring during the laser based direct energy deposition (DED-LB/M) of
Ni-superalloys using in-situ neutron and synchrotron diffraction techniques. The project aimed to enhance
the understanding of the solidification processes and phase evolution in additive manufacturing, specifically for the nickel superalloys IN718 and IN625.
