GGOS IberAtlantic (GGOS IA) functions as a regional node of GGOS, focusing on geodetic activities across the Iberian Peninsula and the Atlantic region. GGOS IA fosters collaboration among geodetic institutions while promoting scientific research and technological development tailored to the region’s unique geophysical characteristics.
CAGGA 2026 Successfully Held in Changsha, China
IAG, 📅 Event UpdateThe Chinese Annual Geodetic General Assembly 2026 (CAGGA 2026) was successfully held from April 17 to 20, 2026 in Changsha, Hunan Province, China. The event was jointly organized by the China National Committee for the International Association of Geodesy (CNC-IAG) and the Geodesy and Navigation Committee of the Chinese Society for Geodesy, Photogrammetry and Cartography (CSGPC).
The assembly brought together more than 2,300 participants from universities, research institutes, and administrative bodies across China, reflecting the strong national engagement in geodetic sciences and their applications.
CAGGA 2026 featured a comprehensive scientific program, including seven high-level forums and seven parallel sessions covering key areas of modern geodesy: precise positioning and reference frames; gravity field and vertical datum; navigation and location-based services; geodetic monitoring and geodynamics; GNSS monitoring and assessment; marine geodesy; and image geodesy technologies and applications.
The conference showcased a high volume of scientific contributions, with approximately 300 oral presentations complemented by over 500 flash talks and posters. The assembly provided an important platform for scientific exchange, collaboration, and discussion of recent advances in geodesy and related disciplines.
CAGGA 2026 once again demonstrated the vitality and continued development of the geodetic community in China and its active contribution to the global geodetic landscape.

Meet Julia Pfeffer – Early Career Scientist
ECS, IAG, IUGG, 📰 General NewsJulia Pfeffer, a French research engineer with strong expertise in the monitoring of the global water cycle with satellite geodetic measurements. Since September 2020, she has led the activities in satellite gravimetry developed at Magellium with successful outcomes in all projects involved. She is currently leading the ESA SING project aiming at evaluating the performance of the future satellite gravity missions NGGM and MAGIC, the CNES SAGSA project aiming at developing an operational data and service center in satellite gravimetry, and the Copernicus Marine Service F3O project aiming at improving ocean reanalyses and forecasts with the integration of enhanced river discharge datasets.
With a PhD in Geophysics from the University of Strasbourg, she has built extensive experience in scientific research, including four years at the Australian National University in Canberra contributing to the development of the ANU GRACE mascon solution. In 2013, she was awarded a postdoctoral fellowship from CNES, leading to the creation of the ALTIGAPS database to quantify vertical land motions and sea level variations in coastal regions. Her early work focused on assessing surface and groundwater storage changes in the Niger and Amazon river basins using in-situ and satellite geodetic data. She has supervised numerous Master’s and PhD students and played a key role in strengthening expertise in satellite gravimetry within the Earth Observation Unit at Magellium. She has authored over 25 scientific papers, delivered more than 50 international conference presentations, and contributed to the development and open dissemination of several Level 3 and Level 4 geodetic datasets.
