Zusammenfassung
The new generation of geodetic VLBI, VLBI Global Observing System (VGOS), is now regularly observing to produce the best geodetic VLBI data ever, with a thermal noise level of about 3 ps. However, the systematic errors due to angular structure of the radio sources are becoming prominent in these high-precision VGOS observations. It is important to understand, study, and monitor these systematic errors with the aim to model them in geodetic data processing. Improvements have been made to derive structure images and Gaussian components at the four bands (3 – 14 GHz) directly from VGOS observations on a regular basis. We will report the progress and the major challenges in modeling source structure in VGOS observations.
