| 摘 要： | 稳定可靠的时间参考是开展时间码测量的前提。时统设备使用环境复杂，不宜拆卸，因此在对时统设备进行现场校准时面临无法直接获得稳定可靠时间参考的难题。本文提出一种设计思路，基于实时卫星共视技术搭建时间码在线校准系统。该系统采用小型化设计与实时在线数据处理技术，可以在校准现场复现守时实验室标准时间，可广泛应用在时间参数现场校准领域。

| Abstract: | Stable and reliable time reference is the premise of launching time code measurement.The use environment of the time system equipment is complex,it is inconvenient to disassemble,therefore,in the field calibration of the time system equipment,it is not possible to directly obtain the stable and reliable time reference.This paper proposes an idea,designs a time code online calibration system based on real-time satellite common view technology.This system adopts portable design and real-time online data processing technology,restoring the standard time of the time-keeping laboratory at the calibration site,which can be widely used in the field of time parameters on-site calibration. |
