Repeater deception jamming of GNSS receiver means rebroadcasting the satellite navigation signals received. This process does not need to break the decoding structure and the technical implementation is easy. Presently, Beidou user machine excludes the measured signal delay in the baseband signal processing, which may cause misjudgment if the delay threshold is set unreasonable. On the basis of existing anti-interference techniques, this paper presents the Beidou/INS integrated countermeasures for repeater jamming, which can greatly improve the detection probability of this kind of interference and reduce the misjudgment of useful signal.
