Abstract

The invention discloses an atomic clock control method, device and equipment, a storage medium and a computer product, and relates to the technical field of atomic clock control, and the method comprises the steps: determining an operation temperature sequence of an atomic clock in a slidable time window and an atomic clock type when the atomic clock is in a holding stage; calling a corresponding punctuality model based on the atomic clock type and the temperature interval in which the operating temperature sequence in the slidable time window is located; inputting the operating temperature sequence in the slidable time window into the timekeeping model to obtain a predictive control word of the atomic clock in the next time step of the last time step in the slidable time window; and performing frequency correction on the atomic clock based on the predictive control word. The timekeeping precision of the atomic clock in the keeping stage is improved.
