Evaluation of Predictability of Quartz-Crystal Oscillators and other Devices

摘要

Data were collected over varying intervals for several types of devices (quartz-crystal, rubidium, cesium beam oscillators and hydrogen maser) and compared to NAVOBSY USNO MC. An ARIMA and several polynomial models for prediction purposes were evaluated. It is concluded that very simple prediction methods can suffice in maintaining a timing system. (Author)
