SUMMARY:5th IVS Training School on VLBI for Geodesy and Astrometry
DESCRIPTION:The aim of this training school is to prepare for the next generation of VLBI\, both in terms of 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). \nThe 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. \nThe IVS Training School is organized by the IVS Committee on Education and Training (IVS CTE)\nDetails about the school will be made available in due time on the website:\nhttps://www.maanmittauslaitos.fi/en/about-nls/organisation/cooperation-groups/ivs-committee-education-and-training/5th-ivs-training\nFor further information contact Nataliya Zubko (firstname.lastname@nls.fi) \nEvent Category: ivs

SUMMARY:JIVE VLBI School (JVS 2025)
DESCRIPTION:We are pleased to announce that the JIVE VLBI School (JVS 2025) will take place during the week of 15-19 September 2025. \nThe school will be held simultaneously at the Joint Institute for VLBI ERIC (JIVE) in Dwingeloo\, the Netherlands\, and the University of Pretoria\, South Africa. The University of Pretoria will serve as a satellite hub for the school\, with limited participation. We will hold common lectures (in-person and streamed from both venues) and parallel in-person tutorial sessions. \nJVS 2025 will train participants in data processing and imaging of very long baseline interferometry (VLBI) observations. The school will cover lectures ranging from the basics of radio interferometry in general to VLBI in particular. There will be extensive hands-on sessions to process and analyze VLBI data\, with a focus on observations from the European VLBI Network (EVN). A limited number of seats will be available at both locations. \nFurther details\, including registration information and a complete agenda\, will follow in early 2025. For now\, please mark the dates of the school on your calendar! \nContact us at jvs@jive.eu for further information and visit jive.eu/jvs2025. \nWe look forward to welcoming you to the Netherlands or Pretoria in September 2025! \nEvent Category: ivs
