Description

DSS's innovative Elastic Deployable Composite Tubular Roll-Out Boom will provide revolutionary performance when compared to conventional state-of-the-art technologies, and will significantly enhance operations and capability for future NASA missions. The proposed Roll-Out Boom is strong, stiff, lightweight, thin, scalable, compactly-stowed, and fabricated from ultra-lightweight composite materials. The Roll-Out Boom can be used as a self-deploying antenna, electric field antenna, linear actuator, grapple arm, gravity gradient boom, camera support, inspection aid, or as an actuator/structure for deploying payloads, antennas, solar arrays, instrument benches, solar sails, and sunshades. The Roll-Out boom is a very simple concept that integrates an innovative deployment synchronization system to provide controlled, reliable and repeatable deployments, to produce deployments always in a predictable/known direction. The Roll-Out Boom provides exceptional structural performance in a small lightweight package, and is a direct replacement to current state-of-the-art systems. Boom sizes envisioned can be from 0.5-inch to 12-inches in diameter (or greater), with lengths from 1-m to 50-m long (or longer). The significance of the proposed technology and program will enable future NASA and non-NASA missions by providing a revolutionary and positive performance impact to the end-user, and allow for the rapid insertion of this mission-enabling technology for future applications.

Description

It is proposed to develop desensitized optimal filtering techniques and to implement these algorithms in a navigation and sensor fusion tool kit. These proposed desensitized optimal filtering techniques include recent advances in robust and/or adaptive generalized Kalman and Sigma-Point filters for non-Gaussian problems with uncertain error statistics, as well as a proposed new technique to desensitize the Kalman filter with respect to parameter uncertainties using a robust trajectory optimization approach called Desensitized Optimal Control. These techniques will be implemented in a relatively generic environment which enables the user to import dynamics and measurement models necessary to apply these filtering techniques to a particular navigation and sensor fusion problem. A variety of sensor models and noise distributions will be available for the user to select, and Monte-Carlo analysis capability will be built into the tool kit to enable statistical performance evaluations. The tool kit will also have a modularized structure so that the modules can be readily integrated with other applications.

Description

The Tropical Rainfall Measuring Mission (TRMM) is a joint U.S.-Japan satellite mission to monitor tropical and subtropical precipitation and to estimate its associated latent heating. TRMM was successfully launched on November 27, 1997 at 4:27 PM (EST) from the Tanegashima Space Center in Japan. The TRMM Precipitation Radar (PR), the first of its kind in space, is an electronically scanning radar, operating at 13.8 GHz that measures the 3-D rainfall distribution over both land and ocean, and defines the layer depth of the precipitation. The primary objective of the 3A26 is to compute the rain rate statistics over 5 degree (latitude) x 5 degree (longitude) x 1 month space-time regions. The output products include the estimated values of the probability distribution function of the space-time rain rates at 4 'levels' (2 km, 4 km, 6 km, and path-averaged) and the mean, standard deviation, and probability of rain derived from these distributions. Three different rain rate estimates are used for the high resolution rain rate inputs to the algorithm: (1) the standard Z-R (or 0th-order estimate having no attenuation correction), (2) the Hitschfeld-Bordan (H-B), and (3) the rain rates taken from 2A25. (Fits based on the high resolution inputs from the surface reference technique are output to the diagnostic file for evaluation). This algorithm is based on a statistical procedure. Although the radar team believes that a statistical method of this type should be implemented for TRMM, the method is relatively new and the testing has been carried out only on simulated data and on preliminary TRMM data. Caution on the use of the results is well warranted. Spatial coverage is between 40 degrees North and 40 degrees South, owing to the 35 degree inclination of the TRMM satellite. The data are stored in the Hierarchical Data Format (HDF), which includes both core and product specific metadata applicable to the PR measurements. A file consists of arrays of rain rate data and supporting information, each of dimension 72 x 16, for three fixed heights (2, 4, and 6 km) and the path-averaged rain rates. The file size is about 16 MB (uncompressed). The HDF-EOS "swath" structure is used to accommodate the actual geophysical data arrays. There is 1 file of PR 3A26 data produced per month.

Description

We propose to replace the Gunn Diode Oscillators (GDOs) in NASA?s millimeter- and submillimeter-wave sensing instruments. Our new solution will rely on modern and reliable microwave integrated circuit technology. Specifically our systems will use highly developed microwave oscillators to achieve a low noise and highly stable reference signal in the 10 ? 30 GHz band. Compact amplifiers based on commercial MMIC chips will then increase the signal strength. Finally, our innovative integrated varactor multiplier circuits will be used to increase the frequency to the 60 ? 150 GHz frequency band with high efficiency and minimal added phase noise. With this technology we expect to achieve phase noise and stability comparable to the best Gunn diode oscillators and fundamentally improved output power and frequency agility. The millimeter-wave integrated circuit process and diode technologies are the critical innovative technologies that are required for this research. Through this SBIR project these innovative technologies will be extended to achieve highly compact multipliers for the 60 ? 150 GHz band. These new multipliers will be integrated with highly developed microwave components to achieve a robust and cost efficient replacement for the GDOs presently used in NASA?s Earth Science program.

Description

This data set is part of the NASA Cold Land Processes Field Experiment (CLPX). Parameters include snow depth, surface wetness, surface roughness, canopy, and soil temperature, measured at Fraser, North Park, and Rabbit Ears MSAs on 19-24 February and 25-30 March 2002. CLPX consists of ground, airborne, and satellite measurements of snow and frozen ground. The CLPX uses a set of nested study areas to permit a detailed examination of cold land processes, modeling, and measurement over a wide range of physiographic conditions and spatial scales. The nested study areas are the Large Regional Study Area (LSA) consisting of 4.5 x 3.5 degrees in north-central Colorado and south-central Wyoming, Meso-cell Study Areas (MSAs) that are 25 km x 25 km, Intensive Study Areas (ISAs) that are 1 km2, and Sectors (four sectors per ISA, with 100-m grid spacing per sector). Temporally, the data collection focuses on two seasons, between 2001 and 2004: mid-winter (when conditions are generally frozen and dry) and early spring (a transitional period when both frozen and thawed, dry and wet, conditions are widespread).

Description

This data set contains the monthly primary forcing data "File A" for Phase 2 of the North American Land Data Assimilation System (NLDAS-2). The data are in 1/8th degree grid spacing and range from Jan 1979 to the present. The temporal resolution is monthly. The file format is WMO GRIB-1. The NLDAS-2 monthly primary forcing data were generated from the NLDAS-2 hourly primary forcing data, as monthly accumulation for total precipitation, convective precipitation, and potential evaporation, and monthly average for other variables. The convective precipitation monthly total is the hourly convective fraction multiplied by the hourly precipitation (both from the NLDAS-2 "File A" files), and then summed over all hours of the month. Monthly period of each month is from 00Z at start of the month to 23:59Z at end of the month. The one exception to this is the first month (Jan. 1979) that starts from 00Z 02 Jan 1979, except for the monthly accumulated precipitation and convective precipitation that both start from 12Z 01 Jan 1979. Brief description about the NLDAS-2 hourly primary forcing data can be found from the GCMD DIF for GES_DISC_NLDAS_FORA0125_H_V002 at http://gcmd.gsfc.nasa.gov/getdif.htm?GES_DISC_NLDAS_FORA0125_H_V002. Details about the generation of the NLDAS-2 forcing datasets can be found in Xia et al. (2012). The monthly land surface forcing fields for NLDAS-2 are grouped into two GRIB files, "File A" and "File B". "File A" is the primary (default) forcing file and contains eleven fields. The GRIBTAB file (http://disc.sci.gsfc.nasa.gov/hydrology/grib_tabs/gribtab_NLDAS_FORA_monthly.002.txt) shows a list of parameters for this data set, along with their Product Definition Section (PDS) IDs and units. For more information, please see the README Document at ftp://hydro1.sci.gsfc.nasa.gov/data/s4pa/NLDAS/README.NLDAS2.pdf.
