| 摘 要： | 研制一种面向时间应用的GPS可驯服铷钟。当铷钟被GPS驯服后，它输出的秒信号实时同步于GPS接收机的秒信号。同时，铷钟和GPS接收机之间的时间差的数据通过一个比例积分控制器去校正铷钟的频率准确度。驯服后，两台GPS驯服铷钟之间的时间差小于20ns、频率差小于1E-12/d。使用一台专用的GPS信号处理板和特定的GPS接收机，时间差可小于5ns。

| Abstract: | A GPS disciplined rubidium oscillator is designed for timing application. After disciplined, the rubidium oscillator outputs a second signal which is real-time synchronized to the second signal of the GPS receiver. In the same time, the time difference between the rubidium oscillator and the GPS receiver is processed to calibrate the frequency of the rubidium oscillator through a PI controller. The time difference is less than 10ns，the frequency difference is less than 1E-12/day between two GPS disciplined rubidium oscillator.After a dedicated GPS signal processing board and a particular GPS receiver is used, the time difference can be limited to 5ns. |
