Quantification of Trace Chemicals Using the Vehicle Cabin Atmosphere Monitor

NASA’s Jet Propulsion Laboratory, Pasadena, California A software program analyzes data measured by the Vehicle Cabin Atmosphere Monitor (VCAM) and quantifies the concentrations of trace chemicals detected by VCAM. The software contains a unique way to quantify the signal measured by VCAM, to establish the concentration curve, and to decide which gain mode data to use for concentration estimation. It solves the problem of quantifying the concentration of trace chemicals in the International Space Station (ISS) internal air using the VCAM miniature gas-chromatograph/mass spectrometer instrument.

Improved Math Model for Multiphoto Measurement Systems

Enhanced bundle adjustment demonstrates improved reliability and accuracy with reduced total processor time. Lyndon B. Johnson Space Center, Houston, Texas The bundle adjustment, or more specifically, the colinearity math model it is based on, is undisputedly the most accurate method to perform 3D scene reconstruction from multiple images. It has been the gold standard since first developed in 1957–1959. The limitations of the method have motivated this investigation into how it could be improved.

Global Elevation Data Adaptive Compression Algorithms

These algorithms can be used in applications requiring large databases of graphical information that are deployed via restricted environments, such as tablets and smartphones. Armstrong Flight Research Center, Edwards, California The Global Elevation Data Adaptive Compression Algorithms (GEDACA) were developed to provide compression and rapid decompression of digital terrain maps (DTMs) in constrained computing environments. The primary purpose of these algorithms is to create and utilize highly compressed digital terrain data representing the geographical areas of the entire world to enable Automatic Ground Collision Avoidance Systems (Auto-GCAS) for high-performance fighter aircraft. The data is formatted to be accessible anywhere in the world in real time, and also allows for control of data resolution to support the complete range of high-performance aircraft operations. Other uses include applications that require large databases of graphical information and are deployed via restricted environments, such as tablets and smartphones.

Cassini Science Planning and Sequencing Team Final Sequence Approval Document Generator (Autodoc)

NASA’s Jet Propulsion Laboratory, Pasadena, California Documents, such as reports that are consistent in format, are excellent candidates for automation. Autodoc was designed as a means to automate such reports in order to reduce the amount of labor necessary to produce reports, and to improve the accuracy of the reports.

Exploration Visualization Environment

New user interface is designed to provide a more consistent look and feel for data entry, and a single hierarchy display for traversing the scene. Langley Research Center, Hampton, Virginia The Exploration Visualization Environment (EVE) is a graphical environment for the visualization, analysis, and simulation of engineering data, specializing in aerospace and aeronautic concepts. EVE is based on the history and successful application of the Synergistic Engineering Environment (SEE) and provides much of the same capabilities. These include integration of time-dependent data with detailed graphical models, enhanced user navigation and time controls, synchronized display of data with simulation playback, and cross-platform support of Windows and Linux.
