Position measurements at GNSS station SMR5 in 2023 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 2023. Approximate position in ITRF2014 frame at epoch 2023.5: X=927077.25m, Y=-2195043.59m, Z=-5896521.09m or in (GRS80) ellipsoidal coordinates: lat=68°07'46.850S, lon=067°06'11.599W, 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.
