Invited Seminar: Mega Satellite Constellations Challenges, Opportunities, and Performance Analysis Featuring A/Prof Akram Al-Hourani
Title: Mega Satellite Constellations: Challenges, Opportunities, and Performance Analysis
Date: 20th September 2024 (Fri)
Time: 10:00 AM – 11:30 AM
Venue: Room 303, Seminar Room, Birch Building, Australian National University (ANU)
Abstract:
Massive satellite constellations are currently being deployed in an unprecedented pace aiming to provide an integrated global coverage. In order to design and optimize such networks, it is important to perform both rapid and in-depth evaluations of their performance based on given design parameters. This presentation will provide an overview of the recent challenges and opportunities offered by mega satellite constellations and will explain the suitable performance analysis methods for these massive communication networks. It will present the main constellation models used in practical applications and further introduce theoretical models based on stochastic geometry that facilitate analytic solutions. The presentation then provides modeling examples for obtaining the statistics of satellites' pass duration, handover behavior, and both the downlink and uplink coverage performance.
Biography:
Akram Al-Hourani is an Associate Professor and the Discipline Leader in the Department of Electrical and Electronic Engineering, School of Engineering, RMIT University, Melbourne, Australia. He is also the Deputy Director of the Centre for Opto-electronic Materials and Sensors and the Telecommunication Program Manager (Masters). He obtained his PhD from RMIT University in 2016 and previously worked as a Research and a Development Program Manager in the Satellite and Telecommunication industry, where he directed industry projects valued at over $120 million. With his expertise, he is currently engaged in multiple research and industry projects related to satellite communications, synthetic aperture radar, and AI in wireless communications. As the Lead Investigator, A/Prof Al-Hourani played a crucial role in delivering the largest open Internet-of-Things (IoT) network in Victoria in collaboration with five local governments, the Northern Melbourne Smart Cities Network. This project won two prestigious industry awards: the Technology Awards for Excellence from the Municipal Association of Victoria (MAV) and the Smart Cities Award from the IoT Alliance Australia (IoTAA). A/Prof Al-Hourani contributed to over 116 journal articles and conference proceedings and is currently ranked in the top 2% of scientists worldwide according to Stanford University's latest rankings, in both the Career-Long and Single Year Impact categories. He is also a recipient of the Alexander von Humboldt Fellowship for Experienced Researchers 2024 in Spaceborne Synthetic Aperture Radar with the German Aerospace Center (DLR) and a The Academic of the Year Space Award in 2024, Australia. A/Prof Al-Hourani is currently an Associate Editor in multiple high-impact journals, including IEEE Transactions of Aerospace and Electronics, and IEEE Open Journal of the Communication Society. His research interests include Satellite Communications, Radar Systems, Neuromorphic computing, Signal Processing/Machine Learning, and Stochastic Geometry.
