Abstract
Beacon-Based Exception Analysis for Multimissions (BEAM) is an end-to-end method of data analysis intended for real-time fault detection and characterization. It provides a generic system analysis capability for potential application to deepspace probes and other highly automated systems. This article describes in brief the architecture, application, and operating theory of BEAM. BEAM provides a generalized formalism for diagnostics and prognostics in virtually any instrumented system. Consideration is given to all standard forms of data: time-varying (sensor or extracted feature) quantities and discrete measurements, embedded physical and symbolic models, and communication with other autonomy-enabling components such as planners and schedulers. This approach can be adapted to on-board or ofiboard implementations with no change to the basic operating theory. The approach is illustrated with an overview of application types, past validations, and ongoing efiorts.
