Satellite Geodesy and Geodynamics Systems Group Homepage


The Satellite Geodesy and Geodynamics Systems Group is a research and development group for a broad range of Earth science applications. Current areas of special emphasis include the improvement and use of the Global Positioning System (GPS) with attention to measuring the tectonic motion of Southern California, and the use of precision geoid measurements from the upcoming GRACE Mission to understand the large scale movement of mass around the world, including the global water cycle. Other group efforts are optimal combination of GPS and Synthetic Aperture Radar (SAR), ocean radar altimetry (TOPEX/Poseidon and JASON missions), and characterization of GPS timing errors. All these topics involve algorithm and analysis technique improvement (filtering theory, mathematical model improvement, and computational methods), in addition to a considerable interpretive science component. The personnel in the group come from a variety of backgrounds in engineering, physics, and geophysics.
