Rafael Terris-Gallego received M.Sc. degrees in Telecommunication Engineering from the Polytechnic University of Catalonia (UPC) in Barcelona, Spain, and in Digital Communications Systems from Telecom Bretagne (IMT Atlantique) in France, both in 2001. He has over 13 years of experience in the private sector as an engineer specializing in satellite communications. Currently, he serves as a researcher in GNSS at the Institute of Space Studies of Catalonia (IEEC) and teaches at the Autonomous University of Barcelona (UAB) and the Open University of Catalonia (UOC). In 2024, he earned his Ph.D. in the field of GNSS authentication from the Signal Processing for Communications and Navigation (SPCOMNAV) research group.

Dr. Ignacio Fernandez-Hernandez has led the design and development of Galileo high accuracy and authentication services at the European Commission, DG DEFIS. He holds degrees in engineering from ICAI, Madrid; an MBA from LBS, London; and a PhD in Electronic Systems from Aalborg University. He is a visiting professor at KU Leuven.

José A. López-Salcedo received his M.Sc. and Ph.D. degrees in telecommunication engineering from Universitat Politècnica de Catalunya in 2001 and 2007, respectively. Since 2006, he has been with Universitat Autònoma de Barcelona, where he is currently a Professor and Head of the Telecommunication Unit. From 2011 to 2019, he also served as Coordinator of the Telecommunication Engineering degree. Additionally, he is affiliated with the Institute of Space Studies of Catalonia (IEEC) and has held several visiting appointments at the University of Illinois Urbana-Champaign, the University of California, Irvine, and the European Commission Joint Research Center. His research interests focus on the convergence of GNSS, 5G/6G, and LEO satellites for positioning, navigation, and timing. He serves as Secretary and Treasurer of the Spanish Chapter of the IEEE Aerospace and Electronic Systems Society, member of the Editorial Committee of the Korean Institute of Positioning, Navigation, and Timing, and elected member of the IEEE Signal Processing Society’s Sensor Array and Multichannel Technical Committee.

Gonzalo Seco-Granados received the PhD degree in telecommunications engineering from the Universitat Politecnica de Catalunya in 2000, and the MBA degree from the IESE Business School in 2002. From 2002 to 2005, he was a Member of the European Space Agency, where he was involved in the design of the Galileo system. He is currently a Professor with the Department of Telecommunication, Universitat Autonoma de Barcelona, where he served as the Coordinator of the Telecommunications Engineering Degree from 2007 to 2010, and as the Vice Dean of the Engineering School from 2011 to 2019. In 2015, 2019, and 2022, he was a Fulbright Visiting Scholar with the University of California at Irvine, USA. He is a co-founder of Loctio, a start-up providing low-energy GNSS positioning solutions for IoT. His research interests include GNSS, and beyond-5G-integrated communications, localization, and sensing. Dr. Seco-Granados is with the Institute of Spatial Studies of Catalonia (IEEC) and an ICREA Academia Fellow. He has been a member of the EURASIP Signal Processing for Multisensor Systems Technical Committee since 2022. Since 2019, he has been the Chair of the Spanish Chapter of the IEEE Aerospace and Electronic Systems Society.
