摘要： 设备时延是卫星双向时间频率传递过程中的主要误差源，对其进行校准是获得高精度时间比对的关键。从卫星双向时间频率传递的基本原理出发，分析了基于移动参考站的卫星双向时间频率传递链路设备时延校准的方法。工程实践中，限于条件对校准方法进行了调整，实现了对两站卫星双向时间比对链路设备时延的校准。

Abstract: Device delay is the main error source in two-way satellite time and frequency transfer system. It is crucial to calibrate the delay in order to achieve highly accurate time comparison. According to the principle of two-way satellite time and frequency transfer, delay calibration based on portable station is introduced for two way satellite time frequency transfer system. In the engineering practice, due to the limit of reality, the method of calibration is modified, and the device delay of two-way satellite time and frequency transfer system is calibrated based on this method.

Key words: Two-way satellite time and frequency transfer, Device delay, +Portable station
