ROSES-16 Amendment 11: New Opportunity in Program Element A.48 Space Geodesy Research Program
The Space Geodesy Program (SGP) has the long-range goal of building, deploying, and operating a next generation NASA Space Geodesy Network (NSGN) of integrated, multi-technique space geodetic observing stations. This infrastructure enables the establishment and maintenance of a precise terrestrial reference frame that is foundational to many Earth observing missions and location-based observations. SGP produces observations that refine our knowledge of Earth’s shape, rotation, orientation, and gravity, advancing our understanding of the motion and rotation of tectonic plates, elastic properties of the crust and mantle, mantle-core interactions, solid Earth tides, and the effects of surface loading resulting from surface water, ground water, glaciers, and ice sheets.
SGP seeks the implementation of NSGN core sites that are comprised of the four major space geodetic observing systems: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), and Doppler Orbitography and Radio-positioning by Integrated Satellite (DORIS). A prototype core site with all four geodetic techniques at NASA’s Geophysical and Astronomical Observatory completed demonstration of next-generation systems in 2013. This site now serves as a model for upgrading and expanding the NSGN as part of NASA’s contribution to the Global Geodetic Observing System (GGOS). The new network is expected to improve the International Terrestrial Reference Frame (ITRF), as well as all other network products (e.g., precision orbit determination), with associated benefits to the supported and tracked missions, science projects, and engineering applications.
Notices of Intent (NOIs) are requested by June 15, 2016, and proposals are due by August 15, 2016
On or about May 11, 2016, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2016” (NNH16ZDA001N) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ and will appear on the RSS feed at: http://nasascience.nasa.gov/researchers/sara/grant-solicitations/roses-2016.
