The dataset was gathered at the Argentinean (Antarctic) research station San Martín in the year 2025. Approximate position in ITRF2014 frame at epoch 2025.5: X=927077.29m, Y=-2195043.62m, Z=-5896521.11m or in (GRS80) ellipsoidal coordinates: lat=68°07'46.850S, lon=067°06'11.597W, h=26.8m, orthometric height above EGM2008 geoid amounts 17.4m. 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.
