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 2015. Approximate position in ITRF2014 frame at epoch 2015.5: X=927077.12m, Y=-2195043.57m, Z=-5896521.12m or in (GRS80) ellipsoidal coordinates: lat=68°07'46.853"S, lon=067°06'11.609"W, 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. Due to harsh environmental conditions the data acquisition between DOY 176 and 209 was interrupted and dataset consists of 333 day files only. Original binary files are of TRIMBLE proprietary format T02. The files of one day have been combined applying UNIX tool "tar" to a day-archive.
