摘要
卫星时间同步是实现自主导航的关键技术之一。提出了利用高轨卫星的转发和跟踪功能实现星间连续、实时双向时间同步的方法。详细阐述了这种方法的原理,分析了该同步方法的误差。结果表明该方法可用于星间自主相对时间同步。
The inter-satellite time synchronization is one of the key techniques to implement the autonomous navigation. A new method of time synchronization is put forward. This method uses transmission of satellite in the high orbit and its tracking function, in order to realize inter-satellite time synchronization in a way of succession, real time, and two way. It explains in detail the principle and synchronization error of the method. The results show that this method can be applied in inter-satellite autonomous relative time synchronization.
