Research on Time Synchronization between Shore and Ship based on Two-way Time-frequeny Transmission

The purpose is to study the application of two-way time comparison method for time synchronization on motion platforms such as ships. Firstly, the one-way time comparison method and the two-way time comparison method are analyzed, and the characteristics of the two methods are compared. Combined with the influence of the motion platform on the time synchronization during movement, an improved two-way comparison time synchronization method suitable for the motion platform is proposed. The time synchronization technique of bidirectional comparison based on carrier ranging principle is discussed, and the conclusion of two-station time synchronization based on carrier bidirectional time comparison under weak relative motion is obtained.
