Description

 

NNH11ZDA001N Release Date: February 18, 2011. Notice of Intent to propose Due: March 18, 2011 through February 8, 2012 Proposals Due: April 29, 2011 through April 30, 2012. RESEARCH OPPORTUNITIES IN SPACE AND EARTH SCIENCES (ROSES) 2011 NNH11ZDA001N, entitled "Research Opportunities in Space and Earth Sciences - 2011 (ROSES-2011)," will be available on or about February 18, 2011, by opening the NASA Research Opportunities homepage at http://nspires.nasaprs.com/ and then linking through the menu listings "Solicitations" to "Open Solicitations." This NASA Research Announcement (NRA) solicits proposals for supporting basic and applied research and technology across a broad range of Earth and space science program elements relevant to one or more of the following NASA Research Programs: Earth Science, Heliophysics, Planetary Science, and Astrophysics.

This announcement seeks innovative approaches to the development of GNSS remote sensing techniques and algorithms to study the Earth’s environment from the ionosphere to Earth’s interior. The coming decade will see a dramatic change both in the number of GNSS satellite constellations and the expansion of signals and frequencies available to civil applications. The changes include the rejuvenation of GLONASS, new GPS III signals, the deployment of QZSS, GALILEO, COMPASS, and GAGAN satellite constellations are among the changes to be expected. These new signals structure will provide a dramatic new opportunity for remote sensing of the Earth system with relatively simple and robust space borne GNSS receivers.

Proposals should focus upon the enhancement of our understanding of the dynamics of the Earth’s surface, atmosphere, and ionosphere through the development of GNSS remote sensing techniques.  The dramatic increase in open GNSS signal structures will significantly increase measurement accuracy and utility. Current applications of GNSS remote sensing focus upon the utilization of refracted GNSS signals via occultation measurement schemes for the characterization of the atmosphere and ionosphere. We seek further development of occultation techniques with a focus upon the broader utilization of existing GNSS signals such as GPS (L1 C/A, L2C and L5) and the GLONASS frequency division multiple access (FDMA) signals in preparation for new spaceborne receiver capabilities. We also seek stronger emphasis on the use of reflected GNSS signals for the characterization of the Earth surface. The reception of GPS reflected signals on airborne and space-borne receivers has been demonstrated using both low and high incident angle reflections. This call seeks proposals to develop and demonstrate algorithms for the recovery surface characteristics including ocean and land elevation, soil moisture, wind stress etc. We also note that combined analysis of reflected and refracted signals have been suggested as a technique for atmospheric tomography, a technique of significant potential benefit to weather and climate studies.
