摘　　要：针对目前航天测控设备时间同步系统的授时来源单一、可靠性不够高、安全性差的问题,应用基于北斗卫星导航系统和全球定位系统的双模授时技术,升级了某型测控设备的时间同步系统,实践证明新的时间同步系统满足设备的应用需求,明显提高了测控设备的可靠性与安全性。Considering the situation that time synchronization system of the aerospace tracking,telemetry and command（TTC）equipment timed by only one source would reduce its reliability and safety,a newly technology called dual-mode timing based on both beidou navigation satellite system（BDS）and global positioning system（GPS）is applied to an old aerospace TTC equipment＇s time synchronization system.It＇s proved that the new time synchronization system meets its requirements fully in practice,and improves its reliability and safety obviously.
