The International Union of Geodesy and Geophysics (IUGG) is the international organization dedicated to advancing, promoting, and communicating knowledge of the Earth system, its space environment, and the dynamical processes causing change.
The International Association of Geodesy (IAG) is one of the five constituent sections of the International Union of Geodesy and Geophysics. The Mission of IAG is the advancement of geodesy. It is implemented by furthering geodetic theory through research and teaching, by collecting, analyzing, modelling and interpreting observational data, by stimulating technological development and by providing a consistent representation of the figure, rotation, and gravity field of the Earth and planets, and their temporal variations.
"The primary objectives of the IERS are to serve the astronomical, geodetic and geophysical communities by providing data and standards related to Earth rotation and reference frames." (IERS)
