Global Navigation Satellite Systems (GNSS) are a critical source of precise positioning, navigation, and timing across various sectors of critical infrastructure, including transportation, energy, and telecommunications. Despite their widespread use, GNSS systems remain vulnerable to both artificial interference and natural disruptions such as space weather. This paper provides a comprehensive overview of the main threats associated with GNSS, detailing their potential impacts on different sectors. In addition to cybersecurity risks, the article also examines environmental factors like solar flares and geomagnetic storms, which can degrade GNSS performance. Specific vulnerabilities in sectors such as aviation, maritime, and industrial automation are analyzed, alongside the probability of occurrence and the varying effects of these risks. Finally, the paper outlines mitigation strategies and identifies future research directions aimed at enhancing the resilience of GNSS-reliant systems.

Global Navigation Satellite Systems (GNSS) have become integral to modern aviation, providing essential positioning, navigation, and timing information. However, the increasing reliance on GNSS has made aviation systems vulnerable to radio frequency interference, particularly intentional jamming. This study compares the effectiveness of Automatic Dependent Surveillance-Broadcast (ADS-B) and a professional GNSS interference detector in identifying jamming at Václav Havel Airport Prague. Over a period of one year, 71,417 flights were analysed, and 37 instances of GPS interference were detected using ADS-B data. Eleven of these instances were also detected by the professional detector, highlighting the potential of ADS-B as a supplementary tool for detecting GNSS interference. This research contributes to the ongoing efforts to enhance the resilience of aviation operations against GNSS jamming.
