Beacon-Based Exception Analysis for Multimissions

BEAM is a method of real-time, automated analysis and diagnosis applicable to a broad class of complex electromechanical systems, including spacecraft, aircraft, and process-control systems. Some aspects of its operation were described in “Reusable Software for Autonomous Diagnosis of Complex Systems” (NPO-20803), NASA Tech Briefs, Vol. 26, No. 3 (March 2002), page 33. Presented here is an expanded overview of the method, outlining its components and their function.
