Global Reference Frame VLBI solution VIE2023 (SX&VG)

Context and methodology Global reference frame solution from Very Long Baseline Interferometry based on IVS data at S/X-band and VGOS Celestial Reference Frame: Source positions are in the J2000 frame, but at the 2015.0 galactic aberration epoch. Reported source position errors are inflated with scaling factors: 1.5 RA, 1.5 De, and a RA/Dec noise floor 30/ 30 micro-arc-sec is applied. Terrestrial Reference Frame: reference epoch 2015.0 and linear velocity Earth Orientation Parameters: reported is one offset per session Technical details GENERATION_TIME: 2024-03-20T21:37:10 DATA_START: 1979-08-03T00:00:00 DATA_END: 2023-12-29T00:00:00 ANALYSIS_CENTER: VIE (TU Wien, Austria) CONTACT: VIE Analysis Center ([e-mail]) SOFTWARE: VieVS v3.2 TECHNIQUE: VLBI FREQUENCY BANDS: S/X + VGOS DESCRIPTION: Earth orientation parameters from the VLBI global solution S/X + VGOS (session-wise reduced parameters)
