Abstract :
Time synchronization is the basic of distributed system, and also is one of the key techniques for solving time offset in space TT&C network. According to the low precision and the bad stability of time synchronization in Internet, this paper designs the scheme of time synchronization in space TT&C network, and proposes the server selection algorithm; finally, the paper proves that the algorithm further improves the accuracy and stability of time synchronization in space TT&C network.
