International GNSS Service Session at AGU26 - Call for Abstracts

[Camille Martire]

Dear Colleagues,


We are pleased to announce that abstract submissions are open for the IGS Session at the next AGU Meeting (07-11 Dec 2026 in San Francisco): G021 - The International GNSS Service (IGS): Leveraging Next-Generation GNSS Data Processing and Analysis Techniques to Secure the Future of Geodesy. The session details are provided below.

We are excited to see sustained progress from our community, especially after our very successful IGS Symposium and Workshop in Santiago de Chile (the recordings and materials of which will be available soon at https://igs.org/workshop/2026/).

We kindly encourage you to submit an abstract to the IGS Session, before the 5th of August 2026 at 2359 EDT (06 Aug 2026 at 0359 UTC). To do so, simply visit https://agu.confex.com/agu/agu26/prelim.cgi/Session/280416.

Please also forward this information to colleagues, working groups, services, early career scientists, or other experts you think might be interested.

We are looking forward to hosting and promoting your contributions !


Thank you very much,
Kind regards,

Camille, on behalf of the G021 Conveners and the IGS Central Bureau.

G021 - The International GNSS Service (IGS): Leveraging Next-Generation GNSS Data Processing and Analysis Techniques to Secure the Future of Geodesy

by Camille Martire, Mara Figueroa, Tom Herring, Scott Luthcke, Rolf Dach

The International GNSS Service (IGS) provides high-precision, openly available, multi-GNSS data and products. This voluntary worldwide federation continues to evolve, pushing the boundaries of geodetic excellence through enhanced, comprehensive, multi-GNSS techniques. As global constellations expand and new architectures emerge in Low Earth Orbit (e.g., LEO-PNT), geodetic data analysis methodologies must quickly adapt. Furthermore, missions like ESA's GENESIS and NASA's GRITSS, focused on unifying the global geodetic reference frame, require the most advanced and rigorous data analysis strategies and inter-technique combinations.
This session invites contributions focused on advancements in GNSS data analysis. Topics of interest include techniques leveraging multi-GNSS and cross-constellation capabilities; strategies incorporating LEO-based observations in geodetic processing; innovative modeling techniques; machine learning applications improving GNSS data analyses; and processing strategies supporting the goals of the GENESIS and GRITSS missions. We specifically welcome presentations highlighting the challenges and solutions in achieving ever-finer geodetic precision in a rapidly evolving GNSS landscape.
