The Model-based Off-Nominal State Identification and Detection (MONSID) system provides robust and reliable fault management capabilities. The MONSID technology is composed of a diagnostic engine and system specific models. MONISD is a relatively compact software package because it relies only on modeling nominal behavior; fault models are not needed. The technique identifies the hardware element that is the cause of the detected fault thereby enabling more targeted recovery/repair response. MONSID supports autonomous operations technology requirements to reduce operations and maintenance costs and minimizes human in the loop intervention. Applied to propellant management and test facilities, the MONSID technology can provide a critical component for autonomous health management of these systems. MONSID provides an evolutionary approach to full onboard autonomy as it can first be implemented and tested in ground-based systems and then migrated to off-world remote operations. Autonomous fault management will be crucial to NASA mission success particularly during critical times where the situation changes rapidly and unpredictably with no opportunity for operator support.
