摘要 本文基于直接溯源方法,实现GNSS时频检测系统向GNSS时间基准溯源,并对时间溯源不确定度评定方法进行了理论分析。该方法具有溯源精度高、可行性强等特点,能够为保证GNSS时统终端的时频参数测量精度提供前提条件。 It has been discussed this paper that the time of time&frequency measurement system is traceable directly to Global Navigation Satellite Systems (GNSS) time standard. The uncertainty evaluating method of time traceability has been analyzed in theory. This way can guarantee the measuring level of GNSS time&frequency terminals with high precision and feasibility.
