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.

Quantum Metrology for Space-Based Tests of Gravitational Physics
This study aimed to develop a framework for studying the effects of spacetime curvature on the propagation of quantum states of light, and to compare them with the propagation of classical light. When distributing entangled photon pairs through a gravitational potential, the effect of spacetime curvature on the properties of quantum states can become significant. This could be relevant for plans to use satellites for global quantum key distribution.
