Synchronization and Visualization of Arbitrary Streams (SAVORS)

Ames Research Center, Moffett Field, California The purpose of SAVORS is to supercharge the command-line tools already used by administrators with powerful visualizations that help them understand the output much more rapidly and with far greater scalability across systems. SAVORS not only supports the output of existing commands, but does so in a manner consistent with those commands by combining the line-editing capabilities of vi, the rapid window manipulation of GNU screen, the power and compactness of Perl expressions, and the elegance of UNIX pipelines.

Using a Moderate Ionospheric Storm Detector to Improve WAAS Availability

NASA’s Jet Propulsion Laboratory, Pasadena, California The Wide Area Augmentation System (WAAS) broadcasts information that allows users to bound the positioning error that arises from ionospheric delay of signals emitted by Global Positioning System satellites. A critical objective of WAAS is to make ionospheric grid delays (IGDs) and grid ionospheric vertical errors (GIVEs) available to users as often as possible.

JLAB Tracking Tool (JTRAK)

Goddard Space Flight Center, Greenbelt, Maryland The JLAB Tracking Tool (JTRAK) is a Web-enabled database tool designed to automate the tracking of James Webb Space Telescope (JWST) Integrated Ground Support System (IGSS) and Integrated Test Support System (ITSS) configured items. These configured items consist of IGSS and ITSS equipment and materials; hardware and software revisions including patch releases of the Science Instrument Development Units (SIDUs) and the Science Instrument Test Sets (SITS); ground lab COTS software license versions and maintenance schedules; and other miscellaneous documents.

Automated Generation of Failure Modes and Effects Document from a Simple SysML Model

NASA’s Jet Propulsion Laboratory, Pasadena, California 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, then run this plugin to produce an Excel spreadsheet.

Space Network Access System (SNAS)

Goddard Space Flight Center, Greenbelt, Maryland 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 system, and is the primary access system for managing TDRSS resources.

Educational Software for OctaSat Nanosatellite Training Kit

Langley Research Center, Hampton, Virginia Nanosatellites are very small satellites that can conduct various space missions using microelectronics, primarily in near-Earth orbits. Aerospace engineering students need to learn about the working principles and control of nanosatellites. However, the cost of an actual nanosatellite system is very expensive and is not suitable for an engineering college-level education. Therefore, this simplified classroom-based simulation kit for nanosatellite was developed, named OctaSat.
