| Session Description | The integration and combination of space geodetic measurements (VLBI, SLR, DORIS, GNSS, satellite altimetry, gravity field missions) is of highest importance to the Global Geodetic Observing System (GGOS). These techniques allow us to measure and monitor with an unprecedented accuracy parameters describing changes on the Earth’s surface as well as the variability of the Earth’s rotation and its gravity field. Their results contribute to a broad range of Earth sciences, especially those supported by ground-based networks in Asia-Oceania areas cooperating with the IAG (International Association of Geodesy) Services. These techniques as well as the CHAMP/GRACE/GOCE gravity field and the Formosat-3/COSMIC missions are integrated within GGOS, providing valuable insights for atmospheric (troposphere and ionosphere) and geodynamical research. Typical examples are space-borne GNSS radio occultation and ground-based GNSS meteorology, crustal deformation, Earth rotation and polar motion, precise orbit determination, positioning and navigation (RTK, PPP), land subsidence, natural hazard monitoring as well as deep-space exploration. A fundamental aspect of this work is the International Terrestrial Reference Frame which is the basis by which we link metric measurements of global change over space, time, and evolving technology, and which is now striving for 1 mm accuracy. This session welcomes all space geodetic techniques issues and their applications in atmosphere and geodynamics. Topics of the session are also the new technological developments that are taking place concerning the above-mentioned techniques, as well as proposals for new geodetic satellite projects and space missions. This session also solicits presentations about ideas, scenarios and simulation studies for future gravity field and altimetry missions. Contributions are welcome on theoretical considerations and simulations to concrete technological realizations and the presentation and interpretation of recent results. |
