摘要

授时是卫星导航系统的基本服务之一，在先进电子设备研制和智能时空信息服务中具有重要作用.针对当前全球卫星导航系统（Global Navigation Satellite System，GNSS）授时方法存在的受地面共视观测站和通信网络限制的问题，本文提出一种基于北斗三号B2b信号的精密单点授时方法（B2b signal based Precise Point Timing，B2b-PPT）.该方法利用北斗三号地球静止轨道（Geostationary Earth Orbit，GEO）卫星播发的B2b信号，结合双频伪距和载波相位观测值，根据精密单点定位算法实时估算接收机钟差.经过世界协调时（Universal Time Coordinated，UTC）偏差改正和硬件延迟校准后，B2b-PPT接收机对本地时钟进行驯服，从而实现高精度时频同步.基于iGMAS（international GNSS Monitoring and Assessment System）观测站的实验结果表明：使用B2b-PPT方法的单站授时精度为0.58 ns，10 h的频率稳定度为

Abstract

Timing is one of the basic services of GNSS(Global Navigation Satellite System) and plays an important role in advanced electronic equipment developing and intelligent spatiotemporal information service. Current GNSS timing methods are limited to common-view station and communication network. To deal with these problems

we propose a precise point timing method based on BDS-3(BeiDou Navigation Satellite System) B2b signal

called B2b-PPT(B2b signal based Precise Point Timing)

which using dual frequency observations and estimating receiver clock by precise point positioning algorithm. After UTC(Universal Time Coordinated) bias correction and hardware delay calibration

the B2b-PPT receiver disciplines the clock to realize precise time-frequency synchronization. Experimental results based on iGMAS(international GNSS Monitoring and Assessment System) stations show that the accuracy of timing using B2b-PPT method is 0.58 ns and the frequency stability at 10 hours is 6.9E-15 in single station mode

corresponding indicators are 0.33 ns and 1.1E-14 respectively in station difference mode. In conclusion

the performance of B2b-PPT method is better than traditional GNSS precise point timing method

and the B2b-PPT method also has the advantage of low cost and being independent of ground communication network and analysis center.
