This thesis addresses the increasingly relevant issue of jamming and spoofing of satellite navigation signals in aviation. The first part of the thesis examines the importance of satellite navigation for aviation and analyses the impact of signal disruptions on commercial flight operations. This is followed by an overview of areas with elevated interference risk in European airspace, supplemented by an analysis of statistical data and trends in interference occurrences in recent years. The concluding section presents a risk assessment conducted on a real case involving a commercial flight that encountered satellite navigation signal disruptions within Slovenian airspace. Furthermore, measures aimed at mitigating risks in the event of such interference are also outlined.
