COTS AI accelerators in mixed-criticality high performance avionics for reconfigurable satellites

Today’s satellites are inherently inflexible and purpose-built for a single mission. In contrast, the community is exploring disruptive approaches towards in-orbit reconfiguration and on-board data processing. One of the most promising approaches is to use COTS components and open source frameworks, which decrease time-to-market and could even increase the pool of developers/users on the satellite.

Plastic Litter Project: Detection and monitoring of artificial plastic targets with satellite imagery and UAV

There is an urgent need to assess the levels of plastic pollution in the ocean, to allow for future monitoring and determine the efficacy of any remediation put into force. As a consequence, parallel to in situ observations, there is a growing interest in detecting marine debris using remote sensing satellite and UAV imagery. The Marine Remote Sensing Group (MRSG) at the University of the Aegean is one of the few groups worldwide with in-deep experience in developing artificial plastic debris target structures, in different configurations and polymer composition.

Solar Particle Radiation Advanced Warning System (SAWS)

Increased radiation levels, as a result of space weather, has been recognised as an important risk for spacecraft and launcher operations. Recently threshold levels of solar energetic particle (SEP) flux and solar activity have been considered as a baseline criteria for launches. After the launch of Gaia in 2013, the transfer included manoeuvres reliant upon the AOCS star trackers, operating in interplanetary space and whose reliability could be seriously impacted by radiation storms known as Solar Particle Events (SPEs).

Development of a dual-channel depolarization lidar technique for the derivation of CALIPSO/Aeolus/EarthCARE-related conversion factors

DEDICAtE, aims to the development of a dual-channel depolarization lidar technique for the derivation of CALIPSO/ADM-Aeolus/EarthCARE-related conversion factors. CALIPSO is capable of retrieving linear particle depolarization ratio at 532 nm in a global scale, providing this well- calibrated product since 2006. Future ESA missions EarthCARE and ADM-Aeolus are based on the employment of the High Spectral Resolution polarization-sensitive lidar technique at 355 nm.
