High-precision time-keeping technology based on rubidium atomic clock
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.
