临潼-蒲城数字微波时间传输系统建设及初步结果

  • [设施]:长短波

  • [摘要]:The micro-wave time transfer system between Lintong and Pucheng has been used to synchronize the time signal from the time-keeping clock room(located in Lintong)and the signal from the broadcast control clock room(located in Pucheng)for over 28 years till the end of 2006.The reliability and the specifications for this time transfer system have been seriously degraded mainly due to the ageing of the device.The technical transformation scheme for the micro-wave time transfer system and the realized function of the digital micro-wave system are introduced briefly.The preliminary results show that the performance of the transformed micro-wave time transfer system has been improved. Abstract:中国科学院国家授时中心的临潼--蒲城微波时间传输系统承担着守时基准钟房(临潼)与发播控制钟房(蒲城)之间的时间同步比对任务。截至2006年底,该系统已经连续工作了28年,由于设备老化等原因,系统的可靠性和性能指标严重下降。概括介绍了微波时间传输系统的技术改造方案和数字微波系统实现的功能,初步结果表明改造后的微波时间传输系统的性能得到了提高。
