Chile – where the crust trembles daily and even a traditional cocktail is nicknamed the “Earthquake” – will become the epicenter of an unprecedented scientific gathering in South America.
On behalf of the Local Organizing Committee, we are pleased to formally announce the International GNSS Service (IGS) Workshop 2026, which will take place from the 1st to the 5th of June 2026 at the Intercontinental Santiago.
The IGS Workshop serves as the premier global forum for advancing GNSS and geodesy. Hosted jointly by the University of Santiago de Chile (USACH) and the Military Geographic Institute (IGM), the 2026 edition will bring together leading experts, researchers, and practitioners to exchange insights, showcase technological breakthroughs, and define the trajectory of global geodetic infrastructure.

EU-wide Community Workshop on Quantum Gravimetry
2026-06-03 - 2026-06-05 | GFZ Helmholtz Centre for Geosciences, Potsdam, Germany
Dear community,
I am very happy to announce the first EU-wide community workshop by the HORIZON EUROPE project “EQUIP-G”. It will take place from 3.6. to 5.6.2026 at GFZ Helmholtz Centre for Geosciences (Potsdam, Germany).
Please see the attached flyer.
This email indents to inform you about this meeting and provide you the possibility to mark the dates in advance in your calendar. We are not yet sure if there will be a hybrid option (most likely not, but information will follow). EQUIP-G in a nutshell: we are developing and deploying a quantum gravimeter network within Europe. This task involves joint activities amongst:

quantum gravimeter instrument testing and metrology
running dedicated use cases across Europe to showcase and investigate this technology with respect to its potential and added value for real world geoscientific and society-relevant applications
develop and test an airborne quantum gravimeter sensor
data management and IT infrastructure for data hosting and sharing following FAIR principles
initiating the creation of a new EPOS technical core service for gravimetry
create an infrastructure in form of a shared park of quantum gravimeters, which hopefully in the future will enable all interested stakeholders to have low-cost access to this new technology

But of course the most important thing is to involve all interested people from the community – you! To shape the future of how, by whom and for what quantum gravimeters will be used and how this technology will develop, also in the European context.
We are eager to meet with the entire community, present first results, exchange ideas, get feedback and opinions and actively use this input! We would be very happy to see many of you attending this workshop and join a lively discussion!
More information will follow in the upcoming months.
If you want to know more about EQUIP-G you can visit our LinkedIn page: https://www.linkedin.com/company/equip-g/ (official project website coming soon!) and/or have a look at the EU Commission information: https://cordis.europa.eu/project/id/101215427.
Best regards,
Marvin Reich (WP lead community building) and the entire EQUIP-G team!
