Prognostic monitoring capabilities for space exploration aircrafts are crucial to enable safety and reliability in these platforms. Nokomis proposes to develop and mature a system which exploits electromagnetic emissions to identify degradation in avionics components and determine the probability of failure and remaining useful life (RUL). Over time, the deterioration of components under stress alters the impedances of circuits, components, integrated circuits, and other electronic subcomponents which cause changes to the electronic emission's signatures. Due to the uniqueness of emission signatures, they can be related directly to specific components within the monitored system. In this Phase I effort, representative avionics components will be artificially aged to the point of failure as they are monitored using Nokomis' AELED based Electronic Health Monitoring (EHM) system. An algorithm will be developed to model the changes in emissions over a component's lifetime, thereby determining the potential for component failure at any point in its operational lifetime.
