The 34th CODATA General Assembly will take place on 17-18 October 2025 in Brisbane, Australia, and online. See the letter from CODATA President convening the General Assembly on the dates following the International Data Week 2025.
The 10th International VLBI Technology Workshop (IVTW) will take place October 21-25, 2025. The meeting will be hosted by Chalmers University of Technology, Onsala Space Observatory, in Gothenburg, Sweden. The scope of the workshop is to encompass all areas of VLBI hardware and software development and techniques on station updates, frontends, backends, recorders, correlation, image processing, potential […]
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 […]
The XVI SIRGAS School will be held in the beautiful city of San Juan, Argentina, with the aim of training professionals in the field of geodesy through the processing of VLBI (Very Long Baseline Interferometry) and SLR (Satellite Laser Ranging) data, key techniques for the definition of global reference frames. The purpose of this course is to provide […]
