Description

technical field [0001] Embodiments of the present invention relate to the field of time-frequency calibration, and in particular, to a method, device, device and medium for generating a standard reference signal. Background technique [0002] With the advancement of science and technology, the fields of satellite navigation, communication engineering, and geographic information science are developing rapidly, all of which require accurate and stable time and frequency standards. Therefore, time-frequency measurement has become one of the most important measurement activities. [0003] As a timing device with high precision, atomic clock is widely used to maintain the performance of the time scale, but the atomic clock is often affected by the noise in the environment, so that the output signal cannot meet the required accuracy. Therefore, how to optimize the atomic clock It is very important to process the output signal to obtain a more accurate standard reference signal. ...
