Canadian Geophysical Union 2026 Scientific Meeting – Call for Abstracts

, , , , ,
The Canadian Geophysical Union (CGU) announces the opening of abstract submissions for the 2026 Scientific Meeting, to be held May 24–27, 2026, in Halifax, Canada. The Geodesy Section will offer a comprehensive program covering advances in gravity field modelling, geoid and height system modernization, GNSS/GNSS-IR, InSAR, geodynamics, deformation monitoring, satellite missions, and innovations in gravimetry. International contributions from the IAG community are encouraged. Travel support for students and Early Career Researchers is available. The abstract submission deadline is January 10, 2026.

Call for Abstracts – EGU26 Session G2.2 “New Technologies for GGOS”

, ,
The Global Geodetic Observing System (GGOS) invites contributions to Session G2.2 “New Technologies for the Global Geodetic Observing System (GGOS)” at the EGU General Assembly 2026 in Vienna. This session will highlight innovations and advances in geodetic observing systems for monitoring Earth’s geometry, gravity, and rotation. Topics include emerging technologies such as relativistic geodesy, quantum sensors, next-generation laser systems, LEO-based positioning, navigation and timing (PNT), and other forward-looking geodetic techniques. The session also welcomes contributions on general GGOS developments, new observatory concepts, and strategies to enhance the global geodetic infrastructure. Join us in shaping the future of geodesy and exploring how cutting-edge technology can strengthen GGOS’s role in observing and understanding our dynamic planet. Abstract Deadline: 15 January 2026, 13:00 CET

GGOS Days 2025 | Report

,
The GGOS Days 2025 took place on 3–5 September within the IAG2025 Scientific Assembly in Rimini, Italy. The event featured five symposia and a highlight session on global geodetic infrastructure, standardization, regional collaboration, AI, space weather, and geohazards. Sessions on Geodesy for Society emphasized data management, policy engagement, and communication, highlighting geodesy’s role in sustainable development. The GGOS Governing Board and Science Panel met in hybrid format to review the implementation plan, update outreach materials, and coordinate capacity-building efforts.

GGOS IberAtlantic School 2025

Highlights from 1st GGOS IberAtlantic Summer School

,
The Yebes Observatory hosted GGOS IberAtlantic’s inaugural Summer School on space geodesy for early-career researchers from Spain and Portugal. Over five days, participants explored GNSS, VLBI, SLR, and gravimetry through theoretical and hands-on sessions, while cultural activities fostered collaboration. The event successfully strengthened geodetic skills, inspired scientific vocations, and built networks across the Ibero-Atlantic region.

IGS Workshop 2026

,
The International GNSS Service Workshop 2026 will be held 1–5 June 2026 at the Intercontinental Santiago, Chile. The workshop will gather global experts in GNSS and geodesy to share insights, showcase innovations, and shape the future of geodetic infrastructure.
