介绍了载波相位平滑伪距的算法及其在双向测距与时间同步系统中的应用。对实测数据的计算和分析表明,载波相位平滑伪距的算法在双向测距与时间同步中的应用能提高双向测距与时间同步系统的测量精度。对测量中发生的伪码错误以及载波相位周跳也给出了处理方法,仿真分析表明这些方法能减小伪码错误和载波相位周跳引起的误差。

The algorithm of smoothing pseudo-range with carrier phase and its application to the dual ranging and time synchronization(DRTS) system are introduced. The calculation and analyses of the measured data show that the application of the algorithm of smoothing pseudo-range with carrier phase to the DRTS can improve the ranging accuracy of DRTS. The processing methods for the pseudo-code mistakes and carrier phase leaps which occurred during the measurements are also given in this paper, and the simulation and analyses show that these methods can reduce the error caused by the pseudo-code mistakes and carrier phase leaps.
