Public award description

SAP PURCHASE REQUISITION: 4200269340 THE CONTROLS AND DYNAMICS BRANCH AT THE NASA GLENN RESEARCH CENTER IN CLEVELAND, OHIO IS CURRENTLY WORKING TO DEVELOP A SENSOR DATA QUALIFICATION SYSTEM (SDQS) FOR NASA S ARES I LAUNCH VEHICLE. AS PART OF THIS EFFORT, NASA IS REQUESTING THE SUPPORT OF EXPERT MICROSYSTEMS, INC., WHICH SPECIALIZES IN SENSOR DATA QUALIFICATION AND ASSOCIATED TECHNOLOGIES. THIS STATEMENT OF WORK DESCRIBES EXPERT MICROSYSTEMS ROLE IN SUPPORTING NASA S EFFORT TO DEVELOP SDQS REQUIREMENTS, DESIGNS, VERIFICATION AND VALIDATION PROCEDURES, AND FEASIBILITY DEMONSTRATIONS IN SUPPORT OF ARES I DEVELOPMENT. THIS EFFORT IS FUNDED BY CONSTELLATION/CREW LAUNCH VEHICLE/UPPER STAGE/AVIONICS. THE CONTRACT PERIOD AND SCOPE MIGHT BE EXTENDED IN THE FUTURE BASED ON NASA S DETERMINATION OF NEED AND THE AVAILABILITY OF FUTURE FUNDING. THIS STATEMENT OF WORK DESCRIBES THE FOLLOWING THREE INITIAL TASKS: TASK 1: CONTRIBUTE TO NASA S SDQS PROOF-OF-CONCEPT STUDY REPORT BY PERFORMING AN INDEPENDENT ANALYSIS OF NASA-SUPPLIED TEST DATA. TASK 2: DETERMINE THE APPLICABILITY AND EVALUATE THE DESIGN OF AN ANALYTICAL REDUNDANCY-BASED DATA QUALIFICATION APPROACH FOR THE ARES I UPPER STAGE LAUNCH ABORT SYSTEM SENSORS. TASK 3: DEVELOP A VIABLE VERIFICATION, VALIDATION AND ACCREDITATION (VV&A) STRATEGY FOR THE ARES I SDQS. NASA RECENTLY CONDUCTED SENSOR FAILURE EVALUATION TESTS ON A FUEL VALVE CHARACTERIZATION TEST RIG AT GLENN RESEARCH CENTER. THE RESULTING TEST DATA CONTAIN HARDWARE SIMULATED SENSOR FAULTS AND SYSTEM FAILURES. IN THIS TASK, EXPERT MICROSYSTEMS WILL INDEPENDENTLY ANALYZE THE NASA-SUPPLIED TEST DATA TO ASSESS AND OPTIMIZE THE PERFORMANCE OF NASA S PROTOTYPE DATA QUALIFICATION SYSTEM OPERATING ON THE TEST DATA. HERE, OPTIMIZATION IMPLIES THE MINIMIZATION OF FALSE DETECTIONS AND MISSED DETECTIONS. A SUCCESSFUL STUDY WILL IDENTIFY STRENGTHS AND WEAKNESSES OF THE PROTOTYPE DATA QUALIFICATION SYSTEM AND THE PROPOSED SDQS APPROACH IN A WAY THAT IS RELEVANT TO ARES I APPLICATIONS. THE STUDY RESULTS WILL BE DOCUMENTED AND SUBMITTED IN A TASK REPORT TO NASA. THIS TASK IS PLANNED FOR PERFORMANCE FROM NOVEMBER 3, 2008 THROUGH MARCH 13, 2009. THE INITIAL TASK DELIVERABLE WILL BE A VIEWGRAPH PRESENTATION DESCRIBING THE INITIAL DATA ANALYSIS RESULTS THAT WILL BE MADE IN A WEBCAST FORMAT TO NASA PERSONNEL ON OR ABOUT JANUARY 9, 2008. THE FINAL TASK DELIVERABLE WILL BE AN INFORMAL WRITTEN REPORT OR ANNOTATED PRESENTATION OF THE EVALUATION STUDY RESULTS THAT WILL BE PROVIDED TO NASA BY MARCH 13, 2009.
