Abstract
There is provided a synchronization device capable of, even when transmission timings of a plurality of other ships are different, almost reliably synchronizing with the other ships during a transmission of a ship concerned and is also provided a synchronization method. The synchronization device, when the ship concerned performs a transmission, obtains timing differences DTi occurring over the past one minute from the transmission timing of the ship concerned (S) and creates a histogram of the timing differences DTi (S). The synchronization deviceselects a class with the highest frequency from classes of the timing differences DTi (S) and obtains a corrected timing DT' associated with the selected class (S). The synchronization devicecorrects a reference timing of the transmission of the ship concerned using the corrected timing DT′ and performs the transmission of the ship concerned (S).
