The proposed SYMPTOM system is consistent with the main objectives of the IVHM component of the NASA Aviation Safety Program. In particular, the SYMPTOM system addresses the problem of detection, identification and mitigation of faults and failures in sensors and sensor suites in aerospace vehicles by fusing system-wide information from diverse and dissimilar sources. Hence the proposed SYMPTOM system can be used in NASA Programs such as the Aviation Safety and Space Exploration Programs where there is a need for a comprehensive FDIA system to improve system safety and integrity in the face of a variety of faults and failures of flight-critical sensors.
The SYMPTOM technology will find applications in minimization of adverse effects of critical sensor failures in manned military aircraft and Unmanned Aerial Vehicles. The SYMPTOM technology is also applicable to ground vehicles, process and power industry, and other fields where there is information available from diverse sources and sensors, and there is a need for minimization of unfavorable effects of sensor faults and failures.
