At the XXIV General Assembly of the International Union of Geodesy and Geophysics (IUGG) held July 2-13 2007 in Perugia Italy the International As- ciation of Geodesy (IAG) also had its quadrennial General Assembly. The IAG - organized and contributed to several Union Symposia as well as to Joint Symposia with other Associations. It also organized ve Symposia of its own one dedicated to eachofitsfourCommissionsanda fthonededicatedtotheGlobalGeodeticObse- ing System (GGOS). This volume contains the proceedings of these ve Symposia which are listed below: Symposium GS001: Reference Frames Convener: H. Drewes Co-convener: A. Dermanis Symposium GS002: Gravity Field Convener: C. Jekeli Co-conveners: U. Marti S. Okubo N. Sneeuw I. Tziavos G. Vergos M. Vermeer P. Visser Symposium GS003: Earth Rotation and Geodynamics Convener: V. Dehant Co-convener: Chengli Huang Symposium GS004: Positioning and Applications Convener: C. Rizos Co-convener: S. Verhagen Symposium GS005: The Global Geodetic Observing System (GGOS) Conveners: M. Rothacher Co-conveners: R. Neilan H. -P. Plag The Symposia were organized based on the structure of the IAG (i. e. one per Commission) and covered the there pillars of geodesy namely geometry Earth ro- tion and gravity eld plus their applications. The inclusion of the Symposium on GGOS - which is no longer a project but a major component of the IAG - integrated all geodetic areas and highlighted the importance of multidisciplinarity in and for geodetic research.
