Commission 3
Advancing research on Earth rotation and geodynamics
Commission 3 studies Earth’s dynamic processes through the analysis of geodetic data, focusing on Earth’s rotation, deformation, and internal structure. Its objectives include advancing research on Earth rotation, geodynamics, and natural hazards, while improving models and measurements for accurate geodetic solutions. The commission promotes collaboration, data exchange, and the development of new geodetic techniques to enhance understanding of Earth’s physical processes.
