Impacts of the image alignment over frequency for VLBI Global Observing System
Ming H. Xu, Tuomas Savolainen, James M. Anderson +4
The VLBI Global Observing System, which is the next generation of geodetic VLBI and is called VGOS, observes simultaneously at four frequency bands in the range 3.0--10.7 GHz (expe…
Evidence of the --VLBI position differences being related to radio source structure
Ming H. Xu, Susanne Lunz, James M. Anderson +3
We report the relationship between the --VLBI position differences and the magnitudes of source structure effects in VLBI observations. Because the --VLBI position diff…
The impacts of source structure on geodetic parameters demonstrated by the radio source 3C371
Ming H. Xu, Robert Heinkelmann, James M. Anderson +4
Closure quantities measured by very long baseline interferometry (VLBI) observations are independent of instrumental and propagation instabilities and antenna gain factors, but are…
