摘要
利用GNSS技术,建立河南远程时间频率传递及溯源应用示范站。采用GNSS共视法,搭建可实时溯源至国家原子时标基准的卫星导航时间频率应用平台,建立河南省级时间标准,实现时间频率的远程传递及溯源,时刻偏差绝对值(1天平均)不大于10 ns,溯源(偏差)标准不确定度不大于10 ns,为社会提供高精度的时间频率标准服务。
Using GNSS technology,the establishment of a demonstration station for remote time and frequency transmission and traceability application in Henan is introduced.By adopting GNSS co-viewing method,building a satellite navigation time and frequency application platform which can be traced to national atomic time-scale primary standard in real-time,establishing Henan provincial time standard,realizing remote transmission and traceability of time and frequency,the absolute value of the deviation of the moment(1-day average)is not more than 10 ns,and the standard uncertainty of traceability(deviation)is not more than 10 ns,providing high precision time and frequency standard service for the society.
