Statistical test for GNSS spoofing attack detection by using multiple receivers on a rigid body
EURASIP Journal on Advances in Signal Processing, 2020 Global navigation satellite systems (GNSS) are being the target of various jamming, spoofing, and meaconing attacks. This paper proposes a new statistical test for the presence of multiple spoofers based on range measurements observed by a plurality of ...
