摘　　要：时间信号同步和实时校准是装备研制和试验中普遍面临的工程难题,为实施现场测试和大型试验中时间信号的校准和同步,本文对GPS远距离时间传递方法进行了说明,设计了一种基于GPS的嵌入式远程时间频率校准系统,基于开关网络研制了嵌入式GPS时钟基准,并运用分布式网络化多点校准的模式,实现了多设备内置时钟的实时在线校准。Time synchronization and real-time calibration is a universal problem in equipment development and testing.In order to calibrate and synchronize the time signal in field test and large trial,The paper illustrates the transfer method of GPS remote time and designs an embedded remote time and frequency calibration system based on GPS,which invents the Embedded GPS clock benchmark based on switching network,and actualizes the real time online calibration of multi device with built-in clock by using the distributed network multi-point calibration model.
