Alkis A. Hatzopoulos
Professor Alkis A. Hatzopoulos was born in Thessaloniki, Greece.
He has been with the Department of Electrical and Computer Engineering at the Aristotle University of Thessaloniki since 1981, where now he is a full Professor. Since 2002 he has been elected as the Director of the Electronics Laboratory of the ECE Dept. He was also elected as Associate Teaching Personnel of the Hellenic Open University, Department of Informatics, for twelve years (2004-2017). His research interests include modelling, design and testing of integrated circuits and systems (analog, mixed-signal, high-frequency), three dimensional Integrated Circuits (3D ICs), electronic communication circuits, thin-film transistors, instrumentation electronics, Bioelectronics systems, Space electronics-applications.
Since 2019 he is the Team leader Professor and Systems Engineer of the student team “SpaceDot” of Aristotle University, which designs, develops, and manufactures the “AcubeSAT” nanosatellite under the support of the European Space Agency (ESA) Educational Office in the frame of the ESA’s Fly Your Satellite! 3 (FYS!3) educational program. He is actively involved in educational and research projects, and he is the author or co-author of more than 170 scientific papers in international journals and conference proceedings, book chapters in international textbooks and books in English and Greek. He has been granted a European and American patent.
He has been a member (2010-2018) of the Belgian Research Foundation Committee (FWO Expert panel WT7) for National (Flanders) Grants and Project evaluations. He is a Senior Member of IEEE and he has served as the IEEE Greece CASS-SSCS joint Chapter Chair from 2010 to 2020.
Space Electronics: Challenges and Solutions
A short introduction on the main problems for the electronic systems in space will be provided. The major problem of radiation effects on space electronics will be described and its sources will be analysed. Then some countermeasures and techniques for radiation hardening of electronic circuits and systems will be presented. The problems caused on the electronics by the very cold and extremely hot environment in space conditions will be discussed, as well as other more general problems due to the low temperatures in space. The important topic of Reliability in space missions will be briefly introduced and basic remedies to deal with it will be mentioned. As case presentations the GNSS systems will be shortly discussed first, and then two nanosatellite development cases by our University Team “SpaceDot”, namely the AcubeSat and the PeakSat projects will be also discussed.
