“…Further, to ensure that at least five authentic signals are received, a new receiver with multi‐peak acquisition ability is designed and realised [27, 28]. The inter‐mediate spoofing attack [31, 32] with four spoofing signals is generated and relevant experimental results are displayed. The false alarm rate of RAIM tests in the experiments is set to 1‰.…”

“…As shown in Fig. 10, an inter‐mediate spoofing attack is implemented, which is capable of converting the receiver's tracking loop from locking on authentic signals to spoofing signals by generating spoofing signals synchronised with authentic signals [31, 32]. The TMRAIM method runs on the new designed GPS receiver, and the final experimental results are uploaded to the computer for display.…”

“…Therefore, it is necessary to gradually pull the PVT results to make the variation within the allowable range of sensor error [10]. For example, intermediate spoofing can make the loop gradually controlled by spoofing signal without inter-rupting the tracking state of receiver [11], [12].…”

Vehicle and airborne navigation users are facing more and more complex signal interference and even spoofing. If vehicles and aircraft do not strengthen their anti-spoofing ability, their navigation performance is bound to be adversely affected. global navigation satellite system (GNSS) spoofing technology has gradually become a preferred interference method for spoofer because of its high concealment and great harm. For spoofer, user terminal increasingly adopts GNSS with inertial measurement unit (IMU): tightly-coupled GNSS/IMU, on this basis, user also configures a variety of anti-spoofing techniques to effectively deal with spoofing. Even if spoofer slowly changes user's positioning, if spoofing strategy is unreasonable, it will lead to the violation of parameter rationality of coupled filter output parameters and spoofing observation, which greatly increases the difficulty of spoofing. In view of the above problems, from the perspective of spoofer, in order to effectively counter the non cooperative target of assembling tightly-coupled GNSS/IMU by using GNSS spoofing, this paper establishes GNSS spoofing mathematical model, and proposes a slowly varying spoofing algorithm to avoid tightlycoupled GNSS/IMU with multiple anti-spoofing techniques based on the analysis of the influence mechanism of spoofing on the positioning of tightly-coupled GNSS/IMU, the algorithm proposes a measurement deviation determination method to avoid a variety of anti-spoofing techniques, which can gradually pull the positioning results of coupled system, and successfully avoid anti-spoofing techniques detection of least squares residual receiver autonomous integrity monitoring (RAIM) and parameter rationality check. The experimental results show that the algorithm can gradually change positioning of tightly-coupled GNSS/IMU within 30 s, and the north, east and down displacements basically achieve the spoofing effect, the errors with the expected offset are −0.5 m, 1.9 m and 12.7 m respectively. At the same time, the detection of the above anti-spoofing techniques is avoided. The mean value of test statistics for tightly-coupled system is reduced by 75.4% and does not exceed the alarm threshold, so as to achieve the purpose of spoofing, the effectiveness and high concealment of the spoofing algorithm are proved.
