Dr. Pau Closas, Senior Researcher of the CTTC, is a Guest co-Editor of the Special Issue on “Vulnerabilities, Threats, and Authentication in Satellite-Based Navigation Systems” in the Proceedings of the IEEE.
This special issue addresses various jammers and their effect on different processing stages and overall Global Navigation Satellite System (GNSS) receiver performance. It presents state-of-the-art countermeasures and provides solutions to combat interference and malicious jammers. The 13 overview papers in the issue cover both software processing and hardware components and are written by experts in the field. The primary goal of this issue is to highlight the potential vulnerabilities of GNSSs, delineate effective mitigation approaches, and deliberate on future trends in the field. The papers of this special issue cover the topics of interference classification, detection, and localization; signal authenticity verification; hardwar specific antennas and front-end designs for interference mitigation; and signal and antenna array processing techniques for advanced GNSS receiver designs, including sparse apertures and jammer excision algorithms using time, frequency, or spatial domain as well as joint-variable representations. 2 articles out of these 13 are co-authored by CTTC researchers.
