摘要作为地面通信手段的备份,也为了提供更可靠的时频传输路径,提出了一种基于北斗短报文通信的NIMDO方案,并设计了一套使用更可靠通信的远程时间溯源装置,利用北斗短报文通信传输参考端的时频数据,客户端解析时频数据并完成对客户端NIMDO的驯服。实验结果表明:在短基线条件下,基于北斗短报文通信的NIMDO方案实现了远程时间精确溯源,客户端与参考端间的溯源偏差优于±4ns,溯源偏差的不确定度为3.6ns。

Abstract：As a backup communications on the ground, and also in order to provide a more reliable frequency transmission path, a NIMDO scheme based on Beidou short message communication is proposed, and a set of remote time traceability device using more reliable communication is designed. Beidou short message communication is used to transmit the time-frequency data of the reference end, and the client analyzes the time-frequency data and tames the client NIMDO. The experimental results show that under the condition of short baseline, the NIMDO scheme based on BeiDou short message communication can achieve the precise traceability of remote time, and the traceability deviation between the client and the reference terminal is better than ±4ns, and the traceability deviation is 3.6ns.

Key words： metrology remote time traceability device time-frequency data transmission BeiDou short message
