Abstract

An anti-spoofing technique based on the cooperation of multiple detections is proposed in this paper. A GNSS receiver could detect more than one correlation peak in one processing channel in acquisition when the spoofing signal exists. Signal quality monitoring (SQM) can detect abnormal changes of the correlation peak when spoofing attack on tracking receiver. Generally, receiver gives up the measurements of the abnormal channel to avoid the risk of tracking fault or spoofing signal. This decreases the number of available signals. Receiver autonomous integrity monitoring (RAIM) is capable of detecting and mitigating single error but lack of dealing with multiple errors. This paper proposes a cooperation method of these three techniques which are complementary. Detailed discussion of the method’s procedure and performance are provided in this paper. Simulation results demonstrate that the method is feasible and effective to detect and mitigate multiple spoofing signals.
