摘要
GNSS时间传递技术是卫星导航技术在时间频率领域的重要应用,也是时间传递的主要技术手段之一。随着我国北斗卫星导航系统的不断建设,北斗系统在时间频率领域应用的研究也逐步深入。主要基于北斗卫星导航系统特有的IGSO、MEO、GEO卫星星座,开展了基于北斗共视和载波相位时间传递算法研究,研制了北斗时间传递软件包(PPTSlo),并对其时间传递链路精度、稳定度进行了定性、定量分析,实验结果表明北斗共视时间传递精度优于6 ns,北斗载波相位时间传递精度能达到亚纳秒-纳秒精度。
GNSS time transfer technology is an important application of satellite navigation technology in time and frequency domain, and is also one of the main means of time transfer. With the continuous development of China＇s Beidou satellite navigation system, the applications in the fields of time and frequency based on Beidou also gradually increase. In his work, time transfer algorithm is focused and software package （PPTSlo） is developed using Beidou common view and carrier phase technology, based on specific IGSO, MEO, GEO satellite constellation in Beidou satellite navigation system. The time transfer link accuracy and stability is analyzed by qualitative and quantitative analysis. Experimental results show that Beidou common view time transfer accuracy is better than 6ns, Beidou cartier phase time transfer accuracy can reach sub-nanosecond to nanosecond.
