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.
