N2 - The influence which satellite signal anomalies have on the positioning accuracy is considered in this paper. According to the 2OS (Second-Order Step) threat model of satellite signal anomalies, i.e. TMA (Threat Model A), TMB (Threat Model B), TMC (Threat Model C), the correlation peak characteristics are analyzed and the simulation is made in the 2OS model parameters space. Then the similarities and differences of time-domain waveform signal in the abnormal and normal navigation signal space, the autocorrelation function and the power spectral density are obtained. The results show that if the satellite navigation signal generator appears abnormal, irregular waveform signal will emerge, causing the distortion of the correlation peak of the receiver tracking module and the shape of the tracking curve. This phenomenon will result in the abnormal code correlation, which will affect the receive of satellite signal.
