COMPREHENSIVE ACCELEROMETER DATA ANALYSIS SOFTWARE

DEFINITION AND DESIGN OF SOFTWARE TO FACILITATE POST-FLIGHT CHARACTERIZATION OF THE ACCELERATION ENVIRONMENT OF MICROGRAVITY EXPERIMENTS WILL BE DEVELOPED. ALGORITHMS WILLBE DEFINED TO ANALYZE ACCELERATION DATA, TRANSFORMED INTO THE EXPERIMENT'S COORDINATE SYSTEM, USING TIME AND FREQUENCYDOMAIN TECHNIQUES (TRANSIENT ANALYSIS AND POWER SPECTRAL DENSITY, RESPECTIVELY). A NEW, COMBINED TIME-AND-FREQUENCY DOMAIN ANALYTICAL TOOL-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.
