Position measurements at GNSS station SMR5 in 2024 with links to TRIMBLE binary data files

SMR5 GNSS long-term raw-data series is aimed at contributing to the scientific research of Earth-System-involved global- as well as Antarctic-regional processes, improving International Terrestrial Reference Frame (ITRF) redefinitions, and benefiting society through enhanced GNSS-derived applications and services. The dataset was gathered at the Argentinean (Antarctic) research station San Martín in the year 2024. Approximate position in ITRF2014 frame at epoch 2024.5: X=927077.27m, Y=-2195043.59m, Z=-5896521.08m or in (GRS80) ellipsoidal coordinates: lat=68°07'46.850S, lon=067°06'11.598W, h=26.8m, orthometric height above EGM2008 geoid amounts 17.3m. GNSS receiver: TRIMBLE NetR9 (SN: 5226K50357), GNSS antenna: Zephyr Geodetic 2 w/Dome, PN: 57971-00 (SN: 30976593), Sampling interval: 1 second. Each file covers a time period of one day. Original binary files are of TRIMBLE proprietary format T02. The files of one day have been combined applying UNIX tool tar.

SMR5 GNSS长期原始数据序列旨在支撑涉及地球系统的全球及南极区域过程科学研究，助力国际地球参考框架（International Terrestrial Reference Frame，ITRF）的重新定义工作，并通过优化GNSS衍生应用与服务造福社会。本数据集采集于2024年阿根廷（南极）圣马丁研究站。该站点在ITRF2014框架下2024.5历元的近似坐标为：X=927077.27米，Y=-2195043.59米，Z=-5896521.08米；或采用（GRS80）椭球坐标表示：纬度68°07'46.850″S，经度67°06'11.598″W，大地高26.8米，基于EGM2008大地水准面的正高为17.3米。所用GNSS接收机为TRIMBLE NetR9（序列号：5226K50357），GNSS天线为带穹顶罩的Zephyr Geodetic 2，零件号：57971-00（序列号：30976593），采样间隔为1秒。每份数据文件覆盖单日时段。原始二进制文件采用TRIMBLE专有格式T02，单日数据文件已通过UNIX工具tar完成合并打包。
