The invention provides an autonomous controllable anti-interference
time synchronization method and device based on Beidou, and belongs to the technical field of satellites, and the method specifically comprises the steps: obtaining the distribution data of different
time synchronization modes which are determined to be
time synchronization deviation time periods in different time periods, and employing the distribution data of the time synchronization deviation time periods which are determined to be time synchronization deviation time periods, determining a time synchronization
processing time period and a time synchronization
processing priority in the time period, determining a priority time synchronization
processing time period by using the time synchronization
processing priority, and obtaining time synchronization processing results of different time synchronization
modes in the priority time synchronization processing time period; determining an adjustment processing strategy of the priority time synchronization processing period according to correction processing data in the priority time synchronization processing period and the time synchronization
processing priority when it is determined that correction processing of the target device needs to be carried out in combination with distribution data of different time synchronization
modes in the time synchronization deviation period in the priority time synchronization processing period, and determining the adjustment processing strategy of the priority time synchronization processing period according to the correction processing data in the priority time synchronization processing period and the time synchronization
processing priority; therefore, the accuracy of time synchronization processing is improved.
