Research and Implementation of Beidou-3 Satellite Multi-Band Signal Acquisition and Tracking Method

doi:10.1007/s12204-019-2115-1

Abstract

Abstract: A new acquisition and tracking method is proposed for signal processing under the new signal system structure of Beidou-3 navigation satellite system (BDS-3). By starting with the analysis of the characteristics and signal structure of the new signal, the local replica of the ranging code and the study of the characteristics of the ranging code are completed, which proves that the method in this paper can be used in the subsequent acquisition and tracking process. The fast Fourier transformation (FFT) search based on longer coherence time and the adaptive phase-frequency switching carrier tracking loop are proposed for signals in different modulation modes. The actual signal of Beidou-3 satellite is sampled by local experiment, and the acquisition and tracking of the Beidou-3 satellite multi-band signal is finally completed. The tracking results verify the feasibility of the proposed acquisition and tracking method.
