Abstract :
System integrated clock (SIC) plays an important role in implementing the high-accuracy constellation automatic time synchronization and information exchange. In the establishment of SIC, error and noise are unavoidably introduced. In the paper, various error sources in the process are analyzed at first, and then an error-reduction method under the model of two-way plus common view time comparison is put forward and analyzed. Theory research and simulation experiment show that the constellation time synchronization error is below 10 seconds.
