Abstract

The second reprocessing campaign of historical observations of GNSS satellites at permanent stations located in Ukraine and in the Eastern Europe for GPS weeks 935–1708 (December 7, 1997 – October 6, 2012) was carried out in the GNSS Data Analysis Centre of the Main Astronomical Observatory NAS of Ukraine with using products updated in IGS repro2 and EPN-Repro2 campaigns – precise ephemerides of GPS and GLONASS satellites, coordinates and velocities of reference permanent GNSS stations, etc. The observations was analyzed with the Bernese GNSS Software ver. 5.2 according to the requirements of the EUREF Permanent GNSS Network (EPN), that were valid at that time. In total, observations on 72 GNSS stations, including 48 Ukrainian stations belonging to the following operators of GNSS networks: MAO NAS of Ukraine, Research Institute of Geodesy and Cartography, TNT TPI company (TNT TPI GNSS Network), PJSC System Solutions (System.NET), Lviv Polytechnic National University, UNAVCO, Inc. (USA), were processed. The IGb08 reference frame was realized by applying No-Net-Translation conditions on the coordinates of the IGS Reference Frame stations. As result, the stations’ coordinates in the IGb08 reference frame and the zenith tropospheric delays for all stations were estimated. The mean repeatabilities for components of stations’ coordinates for all weeks (the characteristics of the precision of the received daily and weekly solutions) are in the following ranges: for north and east components – from 0.6 mm to 1.6 mm (average values are 1.02 mm and 0.94 mm respectively), for height component – from 2.2 mm to 5.2 mm (average value is 3.36 mm) with the outlier of 5.79 mm for GPS week 943. The coordinates of the permanent GNSS stations for one weekly solution are presented.

乌克兰MAO NAS的GNSS数据分析中心进行的第二次历史观测后处理活动

摘要

在主站的GNSS数据分析中心进行了第935-1708周（1997年12月7日至2012年10月6日）在乌克兰和东欧的固定站进行的GNSS卫星历史观测的第二次再处理活动。乌克兰天文台NAS，使用在IGS repro2和EPN-Repro2活动中更新的产品-GPS和GLONASS卫星的精确星历，参考永久GNSS台站的坐标和速度等。使用Bernese GNSS软件ver。版对观测结果进行了分析。5.2根据EUREF永久GNSS网络（EPN）的要求，当时有效。总共对72个GNSS站进行了观测，包括属于以下GNSS网络运营商的48个乌克兰站：乌克兰MAO NAS，大地测量与制图研究所，TNT TPI公司（TNT TPI GNSS网络），PJSC系统解决方案（系统。 NET），利沃夫理工大学，UNAVCO公司（美国）进行了处理。IGb08参考系是通过在IGS参考系站的坐标上应用无净平移条件来实现的。结果，估算了所有台站在IGb08参考帧中的台站坐标和天顶对流层延迟。
