This effort ports the Core Flight Executive (cFE)/Core Flight System (CFS) flight software architecture to multicore processor platforms, and provides mission developers with a common, flightready, flexible software environment that supports single, multi-processor, and multicore systems. Currently the...

Efficient support of planetary surface missions typically requires an orbiting asset that acts as a relay point to/from Earth. Orbital relay passes are normally 5 to 15 minutes in duration over any specific landed site. When multiple landed assets are co-located or near-located in the...

As electronic circuits approach submillimeter wavelength frequencies (300 GHz) and higher, the traditional low-loss method of packaging electronic circuits in waveguide modules for guiding the signal requires more attention. The reasons are that circuits at higher frequencies have lower signal...

A scanning LiDAR, by its inherent nature, generates a great deal of raw digital data. To generate 3D imagery in real time, the data must be processed as quickly as possible. One method of discerning time-of-flight of a laser pulse for a LiDAR application is correlating a Gaussian pulse with a...

Partial bitstream relocation (PBR) on field programmable gate arrays (FPGAs) is a technique to re-scale parallelism of accelerator architectures at run time and enhance fault tolerance. PBR techniques have focused on reading inactive bitstreams stored in memory, on-chip or off-chip, whose...

An international team of researchers, led by Penn State, has developed ultrasensitive gas sensors based on the infusion of boron atoms into the tightly bound matrix of carbon atoms known as graphene. The group is composed of researchers from six countries and includes the 2010 Noble laureate and...

This innovation reads in a proprietary formatted binary data format known as Scatterometer Image Reconstruction (SIR), and converts these data files to netCDF-classic format. This software is provided as a command-line tool for Linux/UNIX-based systems, and includes built-in regression testing...

Crewed space vehicle training has always required highfidelity models of vehicle systems. Many of these systems, particularly of the “flow” variety, benefit from modeling the system as a whole, rather than relying only on the interactions between individual components. In general, system properties...

The Time-Scaled Activity Diagram Simulator software simulates and animates time-tagged events as an overlay on activity and internal block diagrams in MagicDraw as a plugin application. “Events” are quite generic and include atomic actions, compound actions, signal and message exchanges, invocations, and...

SequenceMiner was developed to address the problem of detecting and describing anomalies in large sets of high-dimensional symbol sequences. sequenceMiner works by performing unsupervised clustering (grouping) of sequences using the normalized longest common...

CreateMEPReport.pl software is designed to read through a description of observations scheduled to be taken by the instruments onboard the Mars Reconnaissance Orbiter (MRO) spacecraft to categorize the observations, and then present totals for the categories...

The NASA App showcases a huge collection of the latest NASA content in a mobile optimized format, including images, videos on-demand, NASA Television, mission information, news and feature stories, tweets, ISS sighting opportunities, satellite tracking, Third Rock Radio, featured educational content, and much more for iOS and Android...

SNAS is a single, universally accessible, standards-based, full-featured customer interface for performing Tracking and Data Relay Satellite System (TDRSS) planning, scheduling, and real-time service monitoring and control. It consolidates functionality of multiple legacy customer interface systems into a single...

This software queries a model of system in the MagicDraw program and uses that information to create an Excel spreadsheet that represents a basic FMEA (Failure Modes and Effects Analysis). It automates the generation of an FMEA; the user only has to open MagicDraw,...
