The Beidou B1C signal is a new type of navigation signal used by the Beidou III system. Compared with traditional satellite navigation signals, this navigation signal has two significant characteristics: one is the use of BOC(Binary-Offset-Carrier) modulation, and the other is the separation of the data channel and the pilot channel. BOC modulation has multi-peak characteristics, which leads to ambiguity in tracking, while the PCF(Pseudo-Correlation-Function) algorithm can eliminate related secondary peaks of the BOC signal; the separation of the data channel and the pilot channel results in the dispersion of signal energy. Therefore, based on the PCF algorithm, this paper proposes a linear joint tracking algorithm suitable for B1C signals from the perspective of engineering applications. Finally, it is verified that the tracking accuracy of the proposed algorithm is better than the single-component PCF tracking algorithm.
