High-precision time-keeping technology based on rubidium atomic clock
针对铷原子钟守时特性,提出了一种高精度守时技术.该技术采用温度及频率漂移智能分离算法,自动分离出温度和频率漂移特性,并采用多次曲线拟合方式分别拟合出频率漂移和温度特性曲线,在守时过程中分开进行精准补偿,实现铷原子钟高精度的守时.
In the paper,a high-precision time-keeping technology is proposed for the time-keeping characteristics of rubidium atomic clock.It uses intelligent temperature and frequency drift separation algorithms to automatically separate temperature and frequency drift characteristics,and uses multiple curve fitting methods to fit frequency drift and temperature characteristic curves separately.During the time-keeping process,accurate compensation is carried out separately,thus to achieve high-precision time-keeping of rubidium atomic clock.
