A Novel Spoofing Mitigation Method of GNSS Receiver

Abstract:

Spoofing is more malignant to GNSS receiver than noise jamming, both military and civil GNSS users need to detect and avoid spoofing. This paper presents a novel spoofing mitigation method based on multi-antenna receiver architecture. The algorithm strengthen the authentic signals in noise jamming environment, and the algorithm will place null in the direction of spoofer and reset the receiver to tracking the authentic signals when spoofing attack successfully. The rule to distinguish spoofing signal from authentic signal is spoofing transmitters often transmit several signals from the same antenna. The strategy and performance of the proposed method is independent of the spoofer’s complexity and ability. Computer simulation confirm the availability of the algorithm.
