Join us at the IAG 2025 Scientific Assembly from 1 to 5 September 2025, in Rimini, Italy. With the theme "Geodesy for a Changing Environment", the conference will explore critical topics in geodesy across the four IAG Commissions: Reference Frames, Gravity Field, Rotation and Geodynamics, and Positioning and Applications. Additionally, the ggos-days-2025 will be held […]
The annual business meeting of GGOS, known as GGOS Days, was integrated in 2025 with the IAG Scientific Assembly. As a result, there will be no separate meeting as in previous years. Instead it will consist of GGOS reports during the GGOS-related oral and poster sessions and the GGOS Governing Board and Science Panel meeting: […]
We are pleased to announce that the JIVE VLBI School (JVS 2025) will take place during the week of 15-19 September 2025. The 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 […]
An online school on time-variable gravity from GRACE and GRACE-FO satellite missions Satellite gravimetry has become an indispensible tool for studying the earth system. The satellite missions CHAMP, GRACE/GRACE-FO and GOCE along with Satellite Laser Ranging have demonstrated the utility of time-variable gravity data in understanding the mass changes and their transport within and between […]
Towards a National Geodesy Working Group for South Africa Geodesy — the science of measuring the Earth’s shape, orientation, gravity field, and changes over time — is the foundation of […]
IAG collaborates closely with numerous organizations within geodesy and beyond. See the list for details.
