IAG Commission 4

IAG Commission 4 refers to one of the commissions of the International Association of Geodesy (IAG), focusing on satellite geodesy and the precise measurement of the Earth's shape, gravity field, and rotation. This commission promotes research and collaboration in using satellite technology for geodetic studies. Its work contributes to understanding Earth dynamics, improving global positioning systems (GPS), and aiding in natural disaster monitoring and response. Ultimately, IAG Commission 4 plays a vital role in advancing our knowledge of the Earth, which is essential for various applications in science, engineering, and environmental management.
