Angle-based Correlation (AbC), refined astrometry on board a CubeSat, Experiment 156 on OPS-SAT

AbC is a compact on-board algorithm, initially intended for CubeSats, to measure the absolute direction of a distant beacon with optimised accuracy. The AbC environment anticipates a ground pipeline that has been used with OPS-SAT images to diagnose the ADCS. It has been shown that a ground-truth assessment of the satellite's orientation can be made which, with sufficient data, could allow precise re-alignment of multiple sensors. The ESA contract funded the implementation of the on-board algorithm in C++ and its pipeline in Python.

Bio-Inspired Morphing Wing UAV for deployment from HAPS and Orbit

The project demonstrates a proof-of-concept of a next generation bio-inspired morphing wing inspired by academic research of the Peregrine Falcon morphology. Asymmetric span morphing has previously been demonstrated for UAV roll control via in-plane partial span change. This design has full bird-like span change and a unique out-of-plane modality. This offers novel drag reduction characteristics when made to form an airflow channel in conjunction with a fixed surface such as the fuselage, in “cupped wing” flight.

Inflatable Systems for Aerocapture and Aerobraking

This work has primarily focused on establishing scenarios where inflatable devices could be the most useful. Given that these missions rely on aerodynamic drag that results in (potentially significant) heating, the authors have sought to find solutions to minimize heat fluxes acting on the device surface, and especially keeping it within the limits of flexible/foldable TPS materials for the aerocapture scenario.
