Abstract: The present invention discloses a long distance system capable of performing time synchronization with high precision at the minimum cost by transmitting/receiving a time synchronization signal using one of a power line and a communications line that are commonly installed and used between sub-systems constituting a predetermined long distance system, and a time synchronization method performed in the long distance system. The long distance system includes a control sub-system and a plurality of sub-systems. The control sub-system includes a control unit, an atomic clock, and a synchronization generator. The control unit corrects the time of the atomic clock using satellite navigation signals received through a satellite navigation, and the synchronization generator generates a time synchronization signal using time corrected of the atomic clock. Each of the sub-systems includes a time synchronization terminal that is connected with the control sub-system through at least one of the power line and the communications line and performs time synchronization using the time synchronization signal received through one of the power line and the communications line.
