Comprehensive Accelerometer Data Analysis Software

Abstract:

A software definition and design is proposed to facilitate post-flight characterization
of the acceleration environment of microgravity experiments. Algorithms will be defined
to analyze acceleration data, transformed into the experiment's coordinate system,
using time and frequency domain techniques (transient analysis and power spectral
density, respectively). A new combined time and frequency domain analytical tool,
namely wavelet transforms, will be developed, as will methods for quickly scanning
data sets to extract interesting portions. Methods for efficient data handling and
storage are also to be addressed with the design of digital filtering and decimation
schemes to reduce dataset bandwidth and size. The use of commercially available programs
that fulfill some of the requirements of this system will be emphasized for cost-effectiveness.
Platform and input/output media compatibility will be specified to meet the needs
of the microgravity sciences community, as determined by a poll of investigators.
Microgravity research and R&D for the commercialization of space requires an accurate
and useful characterization of the microgravity environment. Software developed under
subsequent phases of this SBIR project would be made into a commercial product for
microgravity investigators, and more generally, the accelerometer community, so that
this acceleration characterization can be easily carried out.
