A novel approach for the direct estimation of the instantaneous Earth rotation velocity
Oleg Titov
Very Long Baseline Interferometry (VLBI) measures two standard observables: group delay and fringe frequency (delay rate). While group delay is widely used to estimate a broad rang…
Parallactic delay for geodetic VLBI and non-orthogonality of the fundamental axes
Oleg Titov, Angelina Osetrova
The Gaia optical astrometric mission has measured the precise positions of millions of objects in the sky, including extragalactic sources also observed by Very Long Baseline Inter…
Serial MultiView: an efficient approach to mitigating atmospheric spatial-structure errors for VLBI astrometry
Jingdong Zhang, Bo Zhang, Shuangjing Xu +4
Atmospheric propagation errors are a main constraint on the accuracy of Very Long Baseline Interferometry (VLBI) astrometry. For relative astrometry, differential techniques can mi…
Resolving VLBI correlator ambiguity in the time delay model improves precision of geodetic measurements
Oleg Titov, Alexei Melnikov, Yulia Lopez
The modern Very Long Baseline Interferometry (VLBI) relativistic delay model, as documented in the IERS Conventions refers to the time epoch when the signal passes one of two stati…
The ICRF-3: Status, plans, and progress on the next generation International Celestial Reference Frame
Z. Malkin, C. S. Jacobs, F. Arias +17
The goal of this presentation is to report the latest progress in creation of the next generation of VLBI-based International Celestial Reference Frame, ICRF3. Two main directions…
