协调世界时（UTC）是世界时间标准，UTC（k）是任何参与实验室k的物理实现。本文介绍了一种基于GNSS的单向实时授时系统，该系统为国家授时中心提供亚纳秒级的UTC（UTC）实现。该系统价格低廉，易于实施，并已通过测试。
Coordinated Universal Time (UTC) is the worldwide standard of time, and UTC (k) is its physical implementation by any participating laboratory k. We describe a one-way real-time time service system that relies on GNSS to provide a realization UTC (NTSC) of China’s National Time Service Center, to a precision of sub-nanosecond. The system is inexpensive, easy to implement, and has been tested.
