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...

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...

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...

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...

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...

Understanding and predicting transition from laminar to turbulent flow in hypersonic boundary layers is an active and important field of research because transitional and turbulent heating can be four or more times higher than laminar heating on...

X-ray survey missions require nested grazing incidence telescopes with a large field of view (1° or larger) and moderately high resolution across the field of view. This cannot be accomplished using flat focal plane detectors. The telescopes have excellent on-axis resolution, but unacceptable...

During on-orbit servicing of non-cooperative satellites, the relative position of the satellite with respect to the servicing vehicle is needed. Non-cooperative satellites do not have devices to assist the pose estimation (such as markers or reflector), so a system that uses the natural features of the...

This solar tracker integrates a camera with a field of view (FOV) large enough to easily image the entire solar disc — co-boresited with a narrow-band spectrometer that measures the frequency of a Doppler shifted line — with an algorithm designed to drive zero Doppler shift rotation axis of the Sun.

Probabilistic modeling Charles River Analytics Cambridge, MA 617-491-3474 www.cra.com NASA has contracted with Charles River Analytics to develop a system to measure and assess astronaut workload. The system for Cognitive Assessment and Prediction to Promote Individualized...

Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm...
