In light of the vulnerability of satellite navigation receiver against replay attack in the above fields, this paper proposes several anti-replay attack techniques of low complexity, i.e., inertial positioning test, clock skew test and Doppler shift test. The simulation results show that Doppler shift test can resist replay attack effectively without additional hardware to the receiver. In addition, compared to SNR test, absolute power test and the other techniques, Doppler shift test has the advantages of low implementation difficulty and high adaptability, which can provide technical support for the security applications of satellite navigation technology in the fields of great concern. 收起
