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.
