Global Reference Frame VLBI solution VIE2025 (SX+VG+K)

Listed in TU Wien Research Data

Context and methodology Global reference frame solution (TRF + EOP + CRF) from Very Long Baseline Interferometry based on S/X-band, VGOS and K-band sessions until 2026.0.

Description

Analyzed with VieVS software package . TRF: station position (epoch 2020.0) and linear velocity EOP: pole coordinates and UT1-UTC reported for 0 UT, CPO reported for the middle of the session CRF: radio source coordinates (J2000 frame at 2015.0 Galactic aberration epoch with 5.8 uas/y GA amplitude).

Formal errors are directly from the adjustment (without any noise floor or inflation) Technical details DATA_START 1979-08-03T00:00:00 DATA_END 2025-12-30T00:00:00 DESCRIPTION VLBI global solution S/X + VGOS + K with TRF+EOP+CRF estimated FREQUENCY BANDS S/X, VG, K ANALYSIS_CENTER VIE (TU Wien, Austria) within Astro2Geo project CONTACT Hana Krasna (hana.krasna@tuwien.ac.at) SOFTWARE VieVS v4.0 TECHNIQUE VLBI Data origin S/X and VGOS: IVS data centers cddis.nasa.gov/archive K band projects BR079, BL115, 128 and BL122: Lanyi et al.
