The IAG's Global Geodetic Observing System (GGOS) provides the means for integrating ground- and spaced-based geodetic observations. Modernizing the existing geodetic infrastructure and homogenizing the processing of geodetic data are essential for consistent observation of Earth's time-variable shape, rotation, and gravity. This session is a forum for discussing ongoing and planned improvements to the geodetic observing systems and for using the observations from these systems to improve our understanding of the dynamic Earth. Contributions on the progress and plans for building next generation geodetic stations are solicited as are contributions on analyzing observations from the new and legacy stations to improve geodetic products such as Earth orientation parameters and reference frames. Contributions on integrating the new stations with the existing geodetic infrastructure are particularly welcome.
