History of the IERS
The International Earth Rotation Service (IERS) was established in 1987 by the International Astronomical Union and the International Union of Geodesy and Geophysics and it began operation on 1 January 1988. It replaced the International Polar Motion Service (IPMS) and the earth-rotation section of the Bureau International de l'Heure (BIH); the activities of BIH on time are continued at Bureau International des Poids et Mesures (BIPM). Since 1 January 2001 the IERS has got a new structure. In 2003 it was renamed to International Earth Rotation and Reference Systems Service.
