Software-Defined Beacon Receiver Implementation Using Frequency Estimation Algorithms

This algorithm yields a more accurate measurement of frequency and signal power than conventional approaches. John H. Glenn Research Center, Cleveland, Ohio The objective of this work was to develop a robust, cost-effective receiver with maximum dynamic range to track the frequency and power variation of a beacon signal. The result was the development of a frequency estimation algorithm that yields a more accurate measurement of frequency and signal power than conventional approaches like a simple FFT (fast Fourier transform) peak search with bin summing, or a phase locked loop (PLL).

CT-CURS: Computed Tomography Cylinder Data Unwrapping-Reslicing & Analysis, v2

John H. Glenn Research Center, Cleveland, Ohio The software for NASA’s Northstar Systems computed tomography (CT) and Picometrix Terahertz CT systems do not have the ability to unwrap and reslice cylindrical CT data to allow top-to-bottom, 2D sheet views of the data. Therefore, it is difficult to size flaws laterally (although viewing slices in the slice view plane allows sizing flaws in the depth [exterior-to-interior] direction). The unwrapped and resliced view would greatly facilitate inspection assessments.

NTTS Search and Reporting

Ames Research Center, Moffett Field, California The NASA Technology Transfer System (NTTS) is a NASA-created technology transfer workflow management system, a schema-less database management system used to track the life-cycle of NASA inventions. It is built on XDB, a NASA homegrown XML database. Because of its schema-less approach to store data, NTTS can host a cluster of distributed XDB nodes, referred to as GridXML data-storage framework (GDX). NTTS stores data associated with different modules like Invention Disclosures, Patent Applications, Contract Grants, and Partnership Agreements, etc. Different communities at NASA use a module or a group of modules to manage their domain workflow. With volumes of heterogeneous data stored in different modules on a schema-less storage framework, the challenge is to provide a flexible query Application Programming Interface (API) to perform traditional relational-model queries. This challenge is addressed by the NTTS Search API, the product of this invention.

Space Weather Database of Notifications, Knowledge, Information — DONKI

Goddard Space Flight Center, Greenbelt, Maryland SW DONKI is a comprehensive Web application for space weather forecasters, scientists, and the general space weather community. It serves as an archive for space weather activities including solar flares, coronal mass ejections (CMEs), solar energetic particles, and geomagnetic storms. An innovative feature of the system is the ability to generate, modify, and store complex linkages between space weather events — creating a comprehensive network of relationships between activities, and identifying potential cause-and-effect paradigms for each space weather event. SW DONKI also provides public access to all human-generated event analysis and notifications produced by the Space Weather Research Center (SWRC) forecasting team at CCMC (Community Coordinated Modeling Center).

Core Flight System (cFS) Software Bus Network Application Version 1.0

Goddard Space Flight Center, Greenbelt, Maryland The Software Bus Network (SBN) is a plug-in component developed for the Core Flight System (cFS) framework that extends the core Flight Executive (cFE) Software Bus (SB) publish/subscribe messaging service across partitions, processes, processors, and networks. This extension is done transparently for cFS software components, such that cFS software components remain unchanged and are unaware of source or destination(s) location.

STARS Finite Element Multidisciplinary Analysis Computer Program

Armstrong Flight Research Center, Edwards, California An efficient, cost-effective, and unique computer program has been developed that analyzes a variety of practical engineering problems. STructural Analysis Routines (STARS) is a fully integrated, multidisciplinary, finite element-based, graphic-oriented analysis tool that combines individual modules to solve complex engineering problems. The range of applications includes structural analysis, heat transfer, linear aerodynamics, and computational fluid dynamics (CFD), as well as coupled linear and CFD-based aeroelastic, aeroacoustics, aerothermoelastic-acoustics, and aeroservoelastic analysis. Because of the tool’s highly integrated nature, it has broad application across many engineering disciplines.

Hazards Analysis Management Tool

Goddard Space Flight Center, Greenbelt, Maryland The Hazard Analysis Management Tool (HAMT) is comprised of a database and user interface that manages hazard analysis information, manages hazard verifications, and manages relationships between hazard attributes and project elements. The tool offers numerous benefits including the ability for multiple users to simultaneously update information, auto-generation of hazard reports, improved data consistency, ability to quickly obtain up-to-date status reports, and the ability to execute complex queries on the hazard information. This tool does not provide a mechanism for the identification of hazards. The tool requires minimal IT overhead and is easily tailored for specific projects and/or user groups. This tool was developed as a support capability, and testing was limited to the operational environment in which it was initially deployed.
