doi:10.3969/j.issn.1674-1579.2013.04.004

Abstract

Abstract: A time synchronization method for regional constellation satellites via estimating the relative clock errors is presented in this paper. The realization principle of this method is introduced, and the system state and measurement equations of clocks are established. Finally, a Kalman filtering algorithm applicable to time synchronization of constellation is designed. Simulation results show that this method is feasible.

Key words: autonomous navigation, time synchronization, relative clock errors, Kalman filtering, regional constellation
