摘要：
A survey of the results of investigations of the frequency instability of output signals of the hydrogen frequency standard is presented. We analyze the causes of development of instability in the measurement range greater than 1000 sec. The influence of the ambient temperature and geomagnetic field is investigated. The methods used to compensate the frequency drift with the help of periodic corrections are described.
