Abstract
A time synchronization system includes: a position information acquisition unit configured to acquire installation position information related to an installation position of a time synchronization target whose time is synchronized; a time synchronization signal acquisition unit configured to receive a positioning signal transmitted from a positioning satellite as a time synchronization signal and acquire, from the time synchronization signal, transmission position information related a position of the positioning satellite and transmission time information at timing when the time synchronization signal is transmitted; and a signal processing unit configured to calculate synchronized time information for the time synchronization target based on the installation position information of the time synchronization target and the transmission position information and transmission time information from the time synchronization signal, and transmit the synchronized time information to the time synchronization target.
