Project Manager for the Space Geodesy Project (SGP), a new NASA initiative started at the end of 2011 in response to the Earth Science Decadal and the National Research Council study “Precise Geodetic Infrastructure.” SGP encompasses the development, operation, and maintenance of a Global Network of Space Geodetic instruments, a data transport and collection system, analysis and the public disseminations of data products required to maintain a stable terrestrial reference system. Ongoing tasks that include:
Project Manager for the Space Geodesy Project and Principal Investigator for the Global Positioning System Laser Retroreflector Array.
