Common-view time planning method suitable for remote comparison of different types of frequency sources

The invention provides a common-view time planning method suitable for remote comparison of different types of frequency sources. The common-view time planning method Sequentially determining common-view starting time, selecting a time change model suitable for an output signal of the tested frequency source according to priori knowledge of the frequency source, determining parameters of the frequency source model for the first time, calculating the variable quantity of the output of the to-be-tested frequency source along with time, determining an optimal tracking period value, and calculating the starting time of any tracking period. According to the invention, the tracking period matched with different frequency sources can be designed according to the performance characteristics of thedifferent frequency sources, so as to adapt to the time change requirements of long-distance and high-precision measurement of the frequency sources, provide support for keeping synchronization amongthe frequency sources of
