| 摘 要： | 介绍了一种利用Kalman滤波器进行原子钟控制的方法, 并对此方法作了改进, 可以把一个原子钟的相位——时间非常精确地控制到时间标准上. 最后, 利用国家授时中心的实测数据对这种方法作了验证, 证明这种方法切实可行, 控制后原子钟与所选择的参数钟UTC(NTSC)的最大钟差不大于10ns.

| Abstract: | A clock disciplined method based on Kalman filter was given, and this method was improved. It could steer one atomic clock phase-time into time standard precisely. At last, this method was checked with the data from National Time Service Center. The experiment results show that the maximum difference between the disciplined clock and the time standard is no more than 10 ns. |
