Computing Efficient Onboard Analysis and Re-Scheduling

The objective is to speed up the responsiveness to onboard decision-making. NASA’s Jet Propulsion Laboratory, Pasadena, California Prior space missions have not routinely used onboard decision-making. The Autonomous Sciencecraft (ASE), flying onboard the Earth Observing One spacecraft, has been flying autonomous agent software for the past decade that enables it to analyze acquired imagery onboard, and use that analysis to determine future imaging. However, ASE takes approximately one hour to analyze and respond.

Tool for Rapid Analysis of Monte Carlo (TRAM) Simulation Data

This tool can be used in any engineering industry that uses Monte Carlo simulations as part of a design and analysis process. Lyndon B. Johnson Space Center, Houston, Texas Spacecraft design is inherently difficult due to the complexity of the systems involved and the expense of testing hardware in a realistic environment. The number and cost of flight tests can be reduced by performing extensive simulation and analysis studies to understand vehicle operating limits and identify circumstances that lead to mission failure. A Monte Carlo simulation approach that varies a wide range of parameters is typically used to generate a large set of test scenarios. The results of these analyses bound the vehicle performance and eventually help certify a spacecraft for flight.

Object-Oriented FITS File Interface for MATLAB

Goddard Space Flight Center, Greenbelt, Maryland The ability to read complicated Flexible Image Transport System (FITS) files in MATLAB was required for analyzing data from the Integrated Science Instrument Module (ISIM) cryovac test campaign for the James Webb Space Telescope (JWST) project. This software was written to fill that specific need, but is more generally applicable.

Integrated Circuit for Radio Astronomy Correlators Supporting Large Arrays of Antennas

NASA’s Jet Propulsion Laboratory, Pasadena, California Radio telescopes that employ arrays of many antennas are in operation, and ever-larger ones are being designed and proposed. Signals from the antennas are combined by cross-correlation. While the cost of most components of the telescope is proportional to the number of antennas, N, the cost and power consumption of cross-correlation are proportional to N2, and dominate at sufficiently large N. As radio telescopes get larger, there is a need to provide digital-signal-processing electronics that are smaller and less power-hungry than would be implied by the extrapolation of existing designs.

BALFIT Version 3.1 Multivariate Regression Analysis and Regression Model Optimization Software

Ames Research Center, Moffett Field, California The software package BALFIT was developed for both the processing of wind tunnel strain-gage balance data and the analysis of more general multivariate experimental data sets. The software uses automatically generated regression models for the analysis. These optimized regression models are the result of the application of a math model search algorithm to a given multivariate data set. This important feature of BALFIT greatly reduces the time it takes to do an analysis. It has also made the prediction of the dependent variable values more reliable because widely accepted objective metrics are used for the regression model term selection.
