| Abstract: | To realize GPS signal rapid acquisition, a method that used 1024 points FFT algorithm was presented in this paper. Real GPS data was acquainted with this method that the feasibility was validated. If the method is implemented in hardware, less hardware source will be utilized to achieve rapid acquisition. |
