Global Reference Frame VLBI solution VIE2023 (SX&VG)

Description

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
