Due to the large and expensive FFT/IFFT core used in the receiver, the cost of realizing the traditional FFT-based fast GPS signal acquisition method is very high. Although some kinds of averaging correlation algorithm can reduce the instant processing points of FFT/IFFT, their noise performance is not promising. This paper proposed a new compress sampling algorithm with high noise immunity for GPS L1 signal acquisition in frequency domain, which allows a smaller and cheaper FFT/IFFT core for fast acquisition unit, and enhances the Signal-to-Noise Ratio (SNR) due to its \"Redundancy\" structure.
