Abstract

The invention relates to a system and method for locking phase and tracing the time synchronization, the said system includes: the receiver of clock source which is used to receive the second impulse signal and state data of clock source; control device for clock phase-lock which is connected with the receiver of clock source, read the state data of clock source and analyses it to choose a route to trace the second impulse signal, and the traced signal is output according to the need of user. Said method includes: a. receiving the second impulse signal from the clock source and state data; b. analyzing the state data of clock source, and according to the analyzed result choose the second impulse signal; c. tracing the second impulse signal by locking phase and output the signal according to need frequence of user. To solve the problem that caused by using the receiving unit of ''Dipper No. 1'' need to provide local parameters which is lack by hand; and at the same time, it solves the unreliable problem that caused by using the GPS as the clock synchronizing system of synchronizing source.

Description

technical field

[0001] The invention relates to a clock synchronization technology in the communication field, in particular to a system and method for tracking clock synchronization by using the master and backup automatic phase-locking of a satellite system. Background technique

[0002] The digital synchronization network is one of the three supporting networks of the communication network. It is an indispensable and important part of the communication network and the key to ensure the clock synchronization of the entire communication network. For the digital communication network, it needs to provide a variety of different application services, from common services to intelligent value-added services, from voice to data, image and other comprehensive services. The coexistence of these integrated services makes the synchronization of the system more and more important.

[0003] The synchronization is the basis for mutual communication between various devices in the commu...
