Abstract

LV2Debug is a fielded software tool for troubleshooting inertial reference units. It uses automated test equipment test results, the knowledge of expert technicians, failure histories, and repair-cost evaluation to lead a technician through the troubleshooting process. This includes confirming that a fault exists, diagnosing the problem, recommending repair actions, and helping to ensure that a repair has been correctly made. The goals of the LV2Debug troubleshooting system, the approach taken to meet these goals, and the overall architecture and operation of the system are described
