摘要

Radio Determination Satellite Service (RDSS) is the advantage and particular characteristics of Beidou, which is different from other satellite navigation systems. According to the rare existing researches of its timing service, this article evaluates timing performance of one-way and two-way using the time series analysis method. Moreover, this paper systematically studies the one-way timing and two-way timing principle and introduces Beidou measured data and analysis method. By analyzing the clock error total curve, the mean value segment, noise situation and timing accuracy, we have the conclusions: (1) one-way timing accuracy is less than 30 ns, and its Root Mean Square (RMS) is less than 6.81 ns; (2) two-way timing accuracy is less than 20 ns, and its Root Mean Square (RMS) is less than 3.60 ns; (3) there exist period switching phenomenon of timing data of one-way and two-way in each beam, and stratification of one-way timing data. These conclusions can be used for the difference compensation of Radio Determination Satellite Service (RDSS), which can provide reference for the clock error consistency of Beidou system, and then improve the system service precision.
