This dissertation develops the theory and provides experimental veri-fication of GNSS interference detection and localization algorithms with datafrom terrestrial- and space-based receivers. The first study o↵ers an ex-perimental demonstration of single-satellite geolocation of broadcast GNSSspoofers and an analysis of various error sources. The second study exploresdual-satellite geolocation of GNSS interference from Low Earth Orbit (LEO)and presents an analysis of interference signals captured in the GNSS frequencybands by two time-synchronized LEO receivers over the Eastern Mediter-ranean, with the emitters being geolocated. The third study investigates atransient space-based GNSS interference source that has caused continental-wide GNSS interference and presents detection and estimation algorithms toidentify the source. Together, these contributions strengthen GNSS securityby providing the theory and experimental verification of GNSS interferencedetection and geolocation algorithms across several platforms.
