Session #1

Keynote 1: Halim Yanikomeroglu, Carleton University, Canada

Title: “Next-After-Next Generation NTN Architecture for Ultra-Connected World 2040”

Abstract: Ultra-connectivity is more than broadband connectivity; the framework includes connectivity, computing, edge intelligence, surveillance, security, sensing, monitoring, positioning, localization, navigation, and more. The humanity will demonstrate its full potential in every dimension (economic prosperity, wellbeing, equal opportunity, environmental, and more), when the communities get ultra-connected with a sustainable, reliable, resilient, intelligent, green/clean/eco-friendly, secure, ubiquitous & affordable, and ultra high-speed “network of networks” with terrestrial (6G/7G) and non-terrestrial (space and stratospheric) components. This is the “ultra-connected world 2040” vision. The talk will contemplate on a novel next-after-next generation NTN (Non-Terrestrial Networks) architecture for realizing this vision.

 Keynote 2: Symeon Chatzinotas, University of Luxembourg, Luxembourg

Title: “Out of This World AI: Nurturing Intelligence in Non-Terrestrial Networks”

Abstract: Non-Terrestrial Networks are inherently designed to provide wide and in some cases global coverage. This unavoidably leads to massive communication systems in terms of satellites, terminals and links to be coordinated and optimized. This talk focuses on the potential of AI as a technological enabler for two main objectives: 1) reducing the computational complexity of large optimization problems for NTN orchestration, 2) reducing the power consumption of on-board operations in regenerative payloads. Promising use cases and recent results will be presented for each objective and future research directions will be discussed.

Bio: Symeon Chatzinotas (MEng, MSc, PhD, FIEEE) is currently Full Professor / Chief Scientist I and Head of the research group SIGCOM in the Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg. In parallel, he is an Adjunct Professor in the Department of Electronic Systems, Norwegian University of Science and Technology and a Collaborating Scholar of the Institute of Informatics & Telecommunications, National Center for Scientific Research “Demokritos”.

Session #2

Keynote 3: Andreas Knopp, Munich University of the Bundeswehr, Germany

Title: “Distribution: a key enabler for future satellite systems”

Abstract: Latest developments in satellite systems have initiated a paradigm change that now gives non-terrestrial components a key role in future networks. However, to comply with the objectives of the ITU recommendation for IMT-2030, state-of-the-art solutions, mainly based on monolithic spacecrafts, will not be sufficient. Cutting-edge approaches exploiting the benefits of distributed architectures and the inherent distributed signal processing solutions are hence of central importance. In this keynote speech, sparse arrays realized with swarms of small satellites are identified as a promising technology to guarantee ubiquitous connectivity from space. On the other hand, distributed antenna architectures on ground can also help avoid bottlenecks in the feeder links design. Perspectives on the potential of these technologies are provided and open research challenges especially in the domain of distributed signal processing, synchronization and swarms formation-flying are highlighted.

Bio: Andreas KNOPP (MEng, MSc, PhD, MBA, SMIEEE) is a German professor of satellite communications technologies. Since 2015, he has been the Chair Holder of Signal Processing and the Director of the Munich Center of Space Communications research facility at the Bundeswehr University in Munich.

 Keynote 4: Zak Kassas, The Ohio State University, USA

Title: “Ad Astra: Navigation with Megaconstellation LEO Satellites”

Abstract: We are witnessing a space renaissance. Tens of thousands of broadband low Earth orbit (LEO) satellites are expected to be launched by the end of this decade. These planned megaconstellations of LEO satellites along with existing constellations will shower the Earth with a plethora of signals of opportunity, diverse in frequency and direction. These signals could be exploited for navigation in the inevitable event that global navigation satellite system (GNSS) signals become unavailable (e.g., in deep urban canyons, under dense foliage, during unintentional interference, and intentional jamming) or untrustworthy (e.g., under malicious spoofing attacks).

This talk will overview the challenges associated with exploiting megaconstellation LEO satellites for navigation purposes, namely their unknown signals, poorly known ephemerides, loose synchronization and oscillator instability, and propagation effects. Next, a framework termed STAN: simultaneous tracking and navigation will be introduced to overcome these challenges. We will present an end-to-end approach, spanning theoretical modeling and analysis, specialized cognitive software-defined radio (SDR) design, practical navigation algorithms, and experimental demonstrations of STAN on ground and aerial vehicles, navigating with multi-constellation LEO satellite signals (Starlink, OneWeb, Orbcomm, and Iridium) to an unprecedented level of accuracy.

He started his academic career in 2014 at the University of California, Riverside; then was an Associate Professor at University of California, Irvine; then was very early promoted to Full Professor and joined The Ohio State University in 2022. Since starting his academic career, his research has attracted more than $26 million in competitive federal grants from ONR, NSF, AFOSR, DOT, NIST, Sandia National Laboratories, among others. He is a Fellow of the Institute of Navigation and a Distinguished Lecturer of the IEEE Aerospace and Electronic Systems Society.
