NASA Goddard Space Flight Center global VLBI quarterly solution
int_2025a provides estimates of the UT1 angle of the Earth orientation
parameters from processing all publicly accessible Very
Long Baseline Interferometry (VLBI) group delays derived from processing
1-hr geodetic VLBI observations since
1990.01.03
through
2025.03.03
,
in total,
472177
group delays
from
12,389
experiments.
Methods of data analysis are described in full detail in Petrov & Kovalev, "The Radio Fundamental Catalog", 2025, The Astrophysical Journal Supplement Series, 276:38 (51pp), doi: 10.3847/1538-4365/ad8c36.
