Performance analysis of novel Joint GPS Anti-jamming and Anti-spoofing detection

Global Positioning System (GPS), a technology integrated into an extensive range of contemporary devices and applications, is increasingly vulnerable to harmful interference, including spoofing and jamming. These hostile actions pose significant risks, causing disturbances that range from minor to critically operational. This study introduces a novel, hybrid countermeasure for GPS systems, combating such threats. Our method incorporates innovative signal processing, Direction of Arrival (DOA) estimation, and an adaptive filter using the Least Mean Squares (LMS) algorithm and Kalman filter. This unique blend effectively suppresses both jamming and spoofing impacts, substantially boosting the resistance and security of GPS systems against such intrusions. A thorough examination of simulated GPS signals, tested under diverse attack conditions, underlines the strength and efficiency of our proposed approach.
