PhD. Joan A. Ruiz-de-Azua (IEEE Member) was born in Barcelona, Spain. He received the degree in aerospace engineering from Supaero (France) and the degree in telecommunications engineering from UPC (Spain) in 2015. He was awarded with the best Master’s thesis on Critical Communications from the Official Spanish Telecommunications Chartered Institute in 2016. Additionally, he received the Ph.D. degree of telecommunications engineering from the UPC (Spain) in 2020. This dissertation contributes to the Internet of Satellites paradigm in which satellites from different stakeholders establish temporal and opportunistic Inter-Satellite Networks because remote satellites want to collaborate between them. He was awarded with the Cum Laude mention for the excellence of his Ph.D. dissertation. He has participated in different aerospace projects, such as the development of Ariane 5 and Ariane 6 ground segment in GTD company. Furthermore, he has participated in five CubeSat missions in the five years, specially remarking the FSSCat mission (winner of the Copernicus Masters competition, and the Sentinel Small Satellite challenge). In this mission, he was responsible for the FSS Experiment payload. Furthermore, he has been the co-advisor of more than 13 Bachelor's and 8 Master's degree dissertations, and 4 PhD students. He has published 18 works in conferences, 16 in journals and 2 book chapters. Currently, he participating in the European SNS JU ETHER project (https://www.ether-project.eu/) and technically leading the national UNICO-5G 6GSatNet project (https://i2cat.net/unico/6gsatnet/). Additionally, he is leading the research on satellite communications in the NewSpace strategy of the Catalan Government. He is the director of the Space Communication Research Group, which aims at contributing to developing novel communications technologies for future Earth Observation and Telecommunications satellite missions. His research interests are linked to satellite networks, non-terrestrial network architectures, disruptive tolerant routing protocols, application of artificial intelligence in satellite communications, integration of SDN/NFV in satellite constellations, and the integration of IoT devices with satellite platforms.

He is currently the Center Chief of the Satellite Information Convergence Application Services Research Center (SICAS) sponsored by the Institute for Information and Communications Technology Promotion, South Korea. He has been the Chairman of the Smart City Committee of 5G Forum in South Korea, since 2018. He is the Vice Chairman of the Korea Institute of Communication and Information Sciences (KICS). He is a member of the KICS, the Institute of Electronics and Information Engineers, and the Korea Information Science Society.

Jorge Querol is Research Scientist and Head of the 6GSPACE lab at the SIGCOM Research Group of the Interdisciplinary Center for Security, Reliability and Trust (SnT) at University of Luxembourg. He received the Ph.D. degree (Cum Laude) in signal processing and communications from the Polytechnic University of Catalonia, Barcelona, Spain, in 2018. Since then, he is the principal investigator and project manager of multiple research projects dealing with AI-accelerated satellite communications, real-time signal processing, 5G non-terrestrial networks, software defined radio transceivers, joint 6G & satellite navigation, and remote sensing platforms. He is also leading the development of 6G-oriented space and satellite communications experimental and interdisciplinary testbeds for high-TRL and industry-driven applications.

Seongkyun Jeong is Associate professor of department of human intelligence robot engineering at Sangmyung University, Korea.
