CAGGA 2026 Successfully Held in Changsha, China

The 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.
