摘要

澳大利亚国家测量研究所一直在开发通过光纤传输时间和频率的方法，着眼于在射电天文学中的应用。本文报道了一种采用伪随机噪声测距的数字时间传输系统，该系统在现场可编程门阵列上实现。该系统在100公里链路上的时间偏差仅为几秒。

Time-transfer over optical fibre using pseudo-random noise ranging

The National Measurement Institute, Australia has been developing methods for time and frequency transfer over optical fibre with an eye towards applications in radio-astronomy. We report here on a digital time-transfer system that uses pseudo-random noise-ranging and is implemented on a Field Programmable Gate Array. The system has demonstrated a time deviation of a few ps on a 100 km link.
