The 5th IVS Training School on VLBI for Geodesy and Astrometry will be held from October 26 to 28, 2025 at Chalmers University of Technology, directly after the 10th International VLBI Technology Workshop (IVTW2025, https://indico.chalmers.se/event/295/ ).

The aim of this training school is to prepare for the next generation of VLBI, both in terms of the technical development and knowledge transfer between generations of researchers. The new VLBI Global Observing System (VGOS) is being installed worldwide and continues to develop.  VGOS promises significant improvement in the accuracy of VLBI results.  Thus, VGOS will be of great importance for geosciences and global change research as part of the Global Geodetic Observing System (GGOS).

The successful development of VLBI technology in the future requires training and educating the young generation of scientists and their familiarization with all aspects of VLBI technology, starting with VLBI station instrumentation receiving and converting the radio signal, data processing and analysis and obtaining the final results, such as Terrestrial and Celestial Reference Frames and Earth Orientation Parameters.

The IVS Training School will be organized by the IVS Committee on Education and Training (IVS CTE, more information at IVS CTE webpage ) and teaching team consisting of excellent experts in the field.

The school will be held at Chalmers University of Technology and the Onsala Space Observatory (OSO), Sweden.

Dates and deadlines:

March 31st - 1st announcement of the school

June 1st - 2nd announcement of the school

August, 15th - School enrollment starts

September, 15th - School enrollment ends
