Time service functions and principle of Navigation System Changhe No. 2 are introduced. Through monitoring and controlling absolute transmission time of Loran-C signal, a method of station-link coarse synchronization based on absolute transmission time of Loran-C signal is presented. It is proved by experiments that this method consumes less time and is more precise than commonly used methods. Besides, the operation is simpler and the signal utilization improved.
