The session description is given below. The deadline for submission of abstracts is JANUARY 15, 2003. All necessary information may be found at http://www.copernicus.org/egsagueug/index.html Looking forward to seeing you in Nice. With best regards, Markus Rothacher Tom Herring Zuheir Altamimi (Conveners of Session G15) ========================================================================== G15 Interactions and Combination of Space Geodesy Techniques (co-sponsored by GI, GD, AS & OS) Space geodetic observation techniques (VLBI, SLR/LLR, GPS/GLONASS, DORIS, as well as altimetry, InSAR, and the gravity missions) contribute significantly to the improvement and understanding of the three major pillars of geodesy: the Earth's geometry (point coordinates and kinematics), Earth orientation and rotation, and the gravity field and its time variations. These three fields interact in various ways and all contribute to the description of processes in the Earth System. Each of the techniques contributes in a different and unique way to these three pillars and should be combined into a consistent integrated global geodetic observing system (IGGOS). We welcome contributions, that deal with comparison and especially the combination methodology of the various techniques at the level of the sites (integrated observatories, collocations, local ties and technical issues), at the level of common processing standards and parameterizations, and at the level of the combined analysis (from a combination of individual parameter types and normal equations to the combination on the observation level). In this context, contributions from (but not limited to) the Combination Research Centers of the IERS and the IERS SINEX Campaign are of great interest. The final goal of a fully integrated observing system would be the combination of all parameter types common to more than one technique and any presentations discussing steps in this direction are encouraged. The list of common parameters includes site coordinates (e.g., time series of combined solutions), Earth orientation parameters, satellite orbits (combined orbits from SLR, GPS, DORIS, Altimetry), atmospheric refraction (troposphere and ionosphere), gravity field, geocenter, etc. The session may also include studies concerning the benefit of using products from one observation technique as input to another technique. -------------------------------------------------------------------------------- Prof. Dr. Markus Rothacher Phone : ++49-89-289-23191 Forschungseinrichtung Satellitengeodaesie Fax : ++49-89-289-23178 Technische Universitaet Muenchen E-mail: markus.rothacher@bv.tum.de Arcisstrasse 21 D-80290 Muenchen / Germany
