G14A:
The Global Geodetic Observing System: Unified Analysis II

Submit an Abstract to this Session



Session ID#: 31467

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