摘要/Abstract

摘要： 全球卫星导航系统（GNSS）广播协调世界时偏差误差（UTCOE）近年来成为卫星导航供应商和用户关注的焦点之一。本文研究了UTCOE的定义，提出了基于中科院国家授时中心保持的协调世界时UTC （NTSC）和国际权度局（BIPM）时间公报的UTCOE间接评估方法，并采用GPS UTCOE直接评估方法对该方法的有效性进行了验证，给出了评估的不确定度预算。利用搭建的GNSS系统时间偏差监测系统输出数据，评估了BDS、GPS、GLONASS的UTCOE。在2018年全年的评估周期内，BDS UTCOE的均方根（RMS）为17.33 ns。BDS、GPS、GLONASS 3大系统的UTCOE的95%统计值分别为35.47、2.08以及8.64 ns。结果表明，BDS、GPS和GLONASS的UTCOE都符合性能承诺，但GPS远优于系统承诺，GLONASS次之，BDS的UTCOE结果临界，且呈现出明显的系统误差特性。BDS的UTCOE具有较大的提升空间。

Abstract: Coordinated universal time offset error(UTCOE) which is the error of broadcasted coordinated universal time offset(UTCO) has become one of the focuses that global navigation satellite system(GNSS) provider and its users are concerned in recent years. This paper studies UTCOE definition, proposes an indirect assessment method of UTCOE based on Coordinated Universal Time(UTC) kept by National Time Service Center( UTC(NTSC)) and circular T bulletin published by International Bureau of Measurement(BIPM).The validity of the method is verified by using direct assessment method of GPS UTCOE. Furthermore, uncertainty budget of the assessment method is also given. The UTCOE of BDS, GPS and GLONASS are assessed utilizing the monitoring data from the running GNSS system time offset monitoring system at NTSC. During the assessment cycle throughout 2018, the root mean square (RMS) of BDS UTCOE is 17.33 ns. The 95% statistical value of UTCOE of BDS, GPS and GLONASS are 35.47、2.08 and 8.64 ns, respectively. The results show that the UTCOE of BDS, GPS and GLONASS all meet their own standard performance specifications. The UTCOE assessment results of GPS are far superior to its performance commitment. GLONASS is the second. BDS UTCOE assessment results are critical and show obvious systematic error characteristic. So, the UTCOE of BDS has a large room for promotion.
