Signal acquiring apparatus of the satellite positioning system receiver, in accordance with an embodiment of the present invention is based on down-sampling, and in the down sampling the satellite signal and the oversampled PRN code, the matched filter size based on the digitized satellite signal to the code resolution and the correlation on a block-by-block basis, the high-speed Fourier transformation to the value output to the correlation result by the number of blocks used in the matched filter in the M pointer. Further, the power value calculated on the basis of the M point fast Fourier transformed value compared to the threshold and the estimated code phase and the rough (coarse) Doppler of the satellite signal, when successfully acquiring the satellite signal, the zero through a fast Fourier transform based on padding (zero padding) to estimate the precision (fine) Doppler.
