In this paper, a new method of clock disciplining based on GPS/BD dual-mode receiver is proposed, which can improve the estimation accuracy of clock bias by fusing the GPS clock bias data and the BD clock bias data. In addition, the use of unbiased FIR filtering algorithm to filter the clock bias data to improve the accuracy of the clock filter. According to the experimental results, the time synchronization precision of the proposed method is 50ns, which is better than that based on single mode GPS and single mode BD time synchronization system.
