Ionosphere impact and corrections for low frequency radars
The use of low microwave frequencies for radars is key.: It enables radar signals from sub-surface sounders to penetrate deep under the Earth surface, it allows minimised temporal decorrelation in Synthetic Aperture Radars observations (e.g L-band SAR) and to generate high quality interferometric products, it opens up the bistatic use of signals of opportunity due to the presence of L-band navigation signals. However these VHF to L-band signals are highly sensitive to the state of the ionosphere which can create strong perturbations, or even block the signal.

Estimation of proton induced single event rate in very deep submicron technologies
More and more space applications and missions are considering the use of deep submicron technologies. Digital CMOS technologies below 65nm are sensitive to proton induced Single Event Effects (SEE) by direct ionisation mechanism. The consequence is a significant increase of SEE rates in flight (up to several orders of magnitude). This effect will be the dominant cause of SEE in orbit for these technologies. This poses a very significant challenge to SEE mitigation methods used in spacecraft electronics.

Mars Ice Access Mission Study

Mars Ice Access Mission is a key robotic precursor mission to future human exploration planning. It is part of ESA’s Exploration Programme, named “Terrae Novae”, encompassing all ESA’s human and robotic activities related to the exploration and utilisation of Earth Orbit, Moon and Mars. The “Mars Ice Access Mission Study” is a Pre-Phase A level study. The objective of the study was to propose a preliminary design of a mission aiming to:

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.

Aerocapture demonstration mission

The AERODEM is an ESA demonstration mission that will implement an aerocapture phase in order to provide an atmospheric ∆V instead of a standard chemical one for orbiting a SpaceCraft around Mars. The aerocapture technique currently studied relies on a discrete event drag modulation technique that modifies only once the aerocapture module ballistic coefficient by separating / retracting the heatshield.

Study on millimeter wave GaN transistors for space applications

GaN-based devices are becoming a key technology for millimeter-wave applications. Because of outstanding material properties, recent advances in GaN device designs provided a sharp increase in performances including high power, high efficiency, reliability, linearity, and compact size. These capabilities are ideally suited for numerous millimeter-wave power applications such as wireless networks and PAs MMIC for Q-band frequency and beyond.

Prototype NIR/SWIR large format array detector development.

Both dark energy missions propose the use of the Teledyne Imaging Systems Hawaii-2RG detector and SIDECAR ASIC. These activities would lead to a European supply of NIR/SWIR detector technology for both these and future science missions. This programme aims at developing a prototype large area hybrid array comprising silicon read-out integrated circuit and HgCdTe photovoltaic sensing layer.
