In Global Navigation Satellite System (GNSS), acquisition process adjusts the code phases of the incoming signal and the local pseudo-random sequence of the corresponding satellite to less than a code chip offset, and generate the correct local carrier frequency. In BD2/GPS Dual-System GNSS, the code chip lengths are different between two systems and the satellite channels are doubled. By using FFT, a fast acquisition method is presented. It is shown that the method can be used for multi-channel and multi-length satellite signals acquisition at one time, the speed is significantly improved and the complexity is reduced than time domain acquisition method.
