摘要
导航传感器间的时间同步是保证全球定位系统/惯性导航系统(GPS/INS)组合导航系统实现的重要前提。详细分析了时间异步产生的原因,归纳了GPS/INS组合导航时间同步的实现思路,阐述了现有的典型时间同步方法。为GPS/INS组合导航系统时间同步设计提供重要参考。
Time synchronization is a crucial prerequisite for GPS/INS integrated sys- tems. In this paper, the causation of time asynchronization is analyzed in detail, and thoughts of implementing time synchronization for integrated systems are described. A sur- vey of existing time synchronization solutions is presented. It is an important reference for design of integrated navigation systems.
