Abstract:
A method for detecting the distortion of a GNSS signal transmitted by at least one GNSS satellite and received by at least one GNSS receiver is disclosed, where the distortion is caused by a GNSS signal generation defect. Initially, at least one autoregressive parametric model of the GNSS signal is determined at the output of a correlation stage of the GNSS receiver. Next, at least one linear prediction error e(n) between the output signal of the correlation stage and the autoregressive parametric model is computed. The linear prediction error is compared to a detection threshold and the distortion of the transmitted GNSS signal is decided when the linear prediction error exceeds the detection threshold.
