Global Reference Frame VLBI solution VIE2025 (SX+VG)
Listed in TU Wien Research Data
Context and methodology Global reference frame solution from Very Long Baseline Interferometry based on IVS data at S/X-band and VGOS until 2026.0.
Description
Analyzed with VieVS software package . The methodology of the analysis follows description in Krásná et al. (2023) .
Technical details DATA START: 1979-08-03T00:00:00 DATA END: 2025-12-30T00:00:00 FREQUENCY BANDS: S/X, VGOS ANALYSIS CENTER: VIE (TU Wien, Austria) CONTACT: Hana Krasna (hana.krasna@tuwien.ac.at) SOFTWARE: VieVS v4.0 TECHNIQUE: VLBI DATA ORIGIN: vgosDB databases from IVS data centers Data format Plain ASCII files.
