针对区域星座自主导航的任务需求,提出了一种基于相对钟差估计的星座自主时间同步方法.介绍了该方法的实现原理,建立了系统状态模型和系统测量方程,并设计了适用于星座时间同步的Kalman滤波算法.仿真结果表明,该方法能够实现星座卫星的时间同步.
Aiming at the task demand of regional constellation autonomous navigation, a method of constellation autonomous time synchronization based on relative clock difference estimation is proposed. The principle of this method is introduced, and the system state model and system measurement equation are established. Simultaneous Kalman Filtering Algorithm The simulation results show that this method can realize the time synchronization of constellation satellites.
