摘　　要：针对新搭建的北斗授时链路存在时延偏差的问题,提出了一种时延模型。采用计数器法和示波器法,实现了北斗授时链路零值及传输链路时延的测量与校准,并进行实验验证。实验结果表明,测量与校准方法达到了亚纳秒量级的精度,可满足大多数北斗授时应用场合的校准需求。In order to solve the problem of delay deviation of the newly built BeiDou timing link,a delay model is proposed.The counter method and oscilloscope method are used to measure and calibrate the zero value of the BeiDou timing link and the delay of the transmission link,which are verified by experiments.The experimental results show that the measurement and calibration method reaches the accuracy of subnanosecond,which can meet the calibration requirements of most BeiDou timing applications.
