Detekcia rušenia signálu GNSS na letiskách

Abstract

Although the Global Navigation Satellite System provides an increased precision in instrument approaches, it is vulnerable to various signal interferences causing either decreased position accuracy or a complete loss of GNSS signal reception. One of the major threats to a GNSS receiver is the intentional interference known as jamming. Incoming airplanes can be seriously endangered by such signal loss. This bachelor’s thesis addresses the detection and classification of possible unintentional and intentional interference and spoofing attacks on airplanes in proximity to the airdrome Žilina. Besides that, other systems which show sufficient reliability are compared. Additionally, critical parts of RNP approach chart map are evaluated. Finally, a device called HackRF ONE is selected to be put in aerodrome proximity for detection of possible GNSS interference. Using this software defined radio as unmanned aerial vehicle alarm and protection system is another suggested possibility.
