BELG GPS 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. Dataset was gathered at the Argentinean (Antarctic) research station Belgrano II in the year 2022. Approximate position in ITRF2014 frame at epoch 2022.5: X=1106002.63m, Y=-763742.29m, Z=-6214255.77m or in (GRS80) ellipsoidal coordinates: lat=77°52'29.282''S, lon=034°37'36.279''W, h=245.9m. Orthometric height above EGM2008 geoid amounts 257.8m. Sampling interval was 15 seconds. GPS receiver was TRIMBLE 5700 (SN: 0440103922), GPS antenna was Ashtech 700936C_M SNOW (SN: 11992). Each of the 365 archive files BELG_2022xxx.tar.gz covers one day and typically consists of four individual files: TRIMBLE proprietary binary file (.dat) and RINEX files (.22o, .22n, .22a). RINEX format version is 2.1.
