摘要

给出了一种北斗授时接收机时延的测试方法。实验采用了北斗系统模拟器和时间间隔计数器。在此过程中，最重要的一步是对模拟器的延迟进行标定。经分析，该方法的不确定度小于1.5ns。利用该方法对我国典型商用授时接收机进行了测试，测试结果如图所示。研究了接收机时延随温度的变化规律。

The study of BeiDou timing receiver delay calibration

This paper gives a test method of BeiDou timing receiver delay. A BeiDou System simulator and a time interval counter were used in the experiments. During the process, the most important step is to calibrate the delay of the simulator. The uncertainty of this method is analyzed to be less than 1.5ns. Using this method, some typical Chinese commercial timing receivers were tested, and the results are shown in figures. The receiver delay variations with temperature have been studied.
