摘要

摘要从 2020 年 5 月 17 日至 2022 年 11 月 26 日（2106-2237 年 GPS 周），国际全球导航卫星系统服务组织（IGS）的所有产品--GPS 和 GLONASS 卫星的精确星历表、全球导航卫星系统常设台站的坐标和速度等--均以 IGb14 参照基准为基础，这是 IGS 发布 ITRF2014 国际地面参照基准后的第二次实现。这一时期位于乌克兰和东欧常设台站的全球导航卫星系统卫星观测数据由乌克兰国家天文台主天文台全球导航卫星系统数据分析中心处理。处理工作使用伯尔尼全球导航卫星系统软件 5.2 版进行。5.2 版伯尔尼全球导航卫星系统软件进行。总共对 344 个全球导航卫星系统台站进行了观测，其中包括属于以下全球导航卫星系统网络运营商的 273 个乌克兰台站：处理了乌克兰 MAO NAS、乌克兰 StateGeoCadastre（UPN GNSS）、PJSC System Solutions（System.NET）、NU Lviv Polytechnic（GeoTerrace）、Navigation and Geodetic Center（NGC.net）、Kiev Institute of Land Relations（KyivPOS）、Coordinate navigation maintenance system of Ukraine（NET.Spacecenter）、E.P.S. LLC、UA-EUPOS/ZAKPOS、TNT TPI company（RTKHUB Network）和 KMC LLC 的观测数据。IGb14 参照系是根据 EPN C2130 目录中 EPN A 级台站坐标的无网平移条件设定的。因此，估算了 IGb14 参考框架中的台站坐标和所有台站的天顶对流层延迟。各周台站坐标各分量的平均重复性（接收到的日解和周解的精度特征）在以下范围内：北分量--从0.62到1.35毫米（平均值为0.98毫米），东分量--从0.73到1.45毫米（平均值为1.09毫米），GPS第2159和2168周的离群值分别为2.39和1.81毫米，高分量--从2.52到6.36毫米（平均值为3.89毫米）。

Propagation of the IGb14 Reference Frame on the Territory of Ukraine Based on Results of the Analysis of GNSS Observations for GPS Weeks 2106–2237

From May 17, 2020 to November 26, 2022 (GPS weeks 2106–2237) all products of the International GNSS Service (IGS)—precise ephemerides of GPS and GLONASS satellites, coordinates and velocities of permanent GNSS stations, etc.—were based on the IGb14 reference frame, the second IGS realization of the release of the International Terrestrial Reference Frame ITRF2014. Observations of GNSS satellites at permanent stations located in Ukraine and in Eastern Europe for this period were processed in the GNSS Data Analysis Centre of the Main Astronomical Observatory (MAO) NAS of Ukraine. The processing was carried out with the Bernese GNSS Software ver. 5.2 according to the requirements of the EUREF Permanent GNSS Network (EPN), that were relevant at that time. In total, observations on 344 GNSS stations, including 273 Ukrainian stations belonging to the following operators of GNSS networks: MAO NAS of Ukraine, StateGeoCadastre of Ukraine (UPN GNSS), PJSC System Solutions (System.NET), NU Lviv Polytechnic (GeoTerrace), Navigation and Geodetic Center (NGC.net), Kiev Institute of Land Relations (KyivPOS), Coordinate navigation maintenance system of Ukraine (NET.Spacecenter), E.P.S. LLC, UA–EUPOS/ZAKPOS, TNT TPI company (RTKHUB Network), and KMC LLC, were processed. The IGb14 reference frame was set by No-Net-Translation conditions on the coordinates of the EPN Class A stations from the EPN C2130 catalogue. As result, the station coordinates in the IGb14 reference frame and the zenith tropospheric delays for all stations were estimated. The mean repeatabilities for components of station coordinates for all weeks (the characteristics of the precision of the received daily and weekly solutions) are in the following ranges: for north component—from 0.62 to 1.35 mm (the average value is 0.98 mm), for east component—from 0.73 to 1.45 mm (the average value is 1.09 mm) with outliers of 2.39 and 1.81 mm for GPS weeks 2159 and 2168 respectively, for height component—from 2.52 to 6.36 mm (the average value is 3.89 mm).
