Abstract

Due to the high dynamic in Satellite Navigation, the vital restriction for P-code Acquisition should be the Doppler frequency offset and large uncertainty of P code. To speed up the P-code acquisition, this paper proposed a novel acquisition method, based on the Local Frequency Folding method (LFF), by folding local frequency cells and generating code with little burden increase. Meanwhile, the coherent integration results storing structure of the method was modified to fit the parallel non-coherent integration, which accelerated the detection process of P-code acquisition. Preliminary result shows that the mean acquisition reduces significantly, with only −2 dB degradation in detection performance. Furthermore, it can be eliminated when the SNR exceed −10 dB.
