Parallactic delay for geodetic VLBI and non-orthogonality of the fundamental axes
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... -

Self-Calibration of wet troposphere delay and clock phase variations for...
The wet tropospheric component and clock phase variations are the most important factors that limit the accuracy of the geodetic VLBI products. These fast fluctuations can be... -
A novel approach for the direct estimation of the instantaneous Earth...
The Very Long Baseline Interferometry (VLBI) measures two standard observables: group delay and fringe frequency (delay rate). While the group delay is widely used for...
