摘要
The present invention relates to a satellite navigation apparatus. The satellite navigation apparatus of the present invention comprises: a first anti-jamming circuit and a second anti-jamming circuit configured to remove a jamming signal from an input signal; and outputs of the first anti-jamming circuit and the second anti-Gt; Each of the first to eighth jamming circuits and the second to eighth jamming circuit is configured to perform windowing, fast Fourier transform, anti-jamming, and inverse fast Fourier transform on the input signal. Anti-jamming involves detecting the frequency of the sample with the maximum magnitude from the resulting signal of the fast Fourier transform, and removing samples corresponding to the reference number around the detected frequency.
