The main objective of this study is the evaluation of the merits of a dual-camera setup for the acquisition of both high spatial resolution images and high-resolution images of identified events of
interest, on-board, through AI methods. A mission analysis of the approach for a single-satellite, dual camera setup as well as for a two-satellite (leading-trailing), single camera setup was

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.

An activity with GSTP Element 1 and Greece has developed a generic alarm management system. Currently, spacecraft operation teams are usually notified of non-nominal conditions when specific system parameters exceed preset threshold values, alerts that do not offer operators a deeper insight into a system’s condition. The Advanced Alarm Management System will: Enhance alarm generation and notification system through advanced processing of the data using industrial grade Complex Event Processing (CEP) technologies.
