We would like to call your attention to Theme 5 "Observing Systems and Services". Please consider submitting a paper for this Theme. Below you find the detailed Theme description. Deadline for the receipt of abstracts is 21 April 2013, with a grace period of a week. http://www.iag2013.org/IAG_2013/Call.html Sincerely, H. Kutterer, R. Barzaghi, S. Bonvalot, U. Hugentobler, B. Luzum, R. Neilan ............................................................................ Theme 5: Observation Systems and Services Theoretical and methodological developments in geodesy have always been accompanied by actual observations of geodetic parameters. Today, continuously operating observing networks and systems are state-of-the-art. Nevertheless, depending on particular tasks, observing in campaigns can still be the best-practice solution. From its beginnings, the IAG has established services which contribute to science and society. An important breakthrough was achieved in the 1990s with the establishment of fully operational IAG services for modern space geodetic techniques, such as the IGS, the ILRS, IDS and the IVS. The definition and establishment of the Global Geodetic Observing System is the logical consequence of such an evolution. Geodetic observatories, and the complex data and analysis infrastructure underpinning the IAG services are the backbone of scientific work in many fields, and in support of geospatial activities in general. Contributions in this Theme are invited in the following topic areas: 1. Theory, methodology and application of observation networks, systems and services. 2. Present challenges for geodetic observatories. 3. Development of geodetic observation and data infrastructure. 4.State-of-the-art of the IAG services. 5.The Global Geodetic Observing System (GGOS). 6.Integrated analysis and combined products of geometry, gravity and Earth rotation. ............................................................................
