A graphical development environment for the Anomaly Monitoring Inductive Software System (AMISS), a health-monitoring software system based on the Intelligent System Division’s Inductive Monitoring System (IMS), has been installed and certified on a dedicated server in the Johnson Space Center Mission Control Center (JSC MCC). This development environment allows users to build and update system models used by real-time International Space Station (ISS) health-monitoring applications running on flight control consoles. Previously, these models were maintained by Ames personnel and transferred to JSC for import into the flight control room. The new MCC-resident AMISS development software provides convenient access within the mission control operations environment for flight control personnel to update models currently installed in the Flight Control Room (FCR) and to develop models for new monitoring capabilities. The initial installation supports ISS thermal, power, life support, attitude control, and other areas covered by the Attitude Determination and Control Officer (ADCO), Environmental and Thermal Operating Systems (ETHOS), Station Power Articulation and Thermal Control (SPARTAN), and Communications RF Onboard Networks Utilization Specialist (CRONUS). Additional capacity is available to accommodate other disciplines as necessary.
BACKGROUND: The Inductive Monitoring System (IMS) is an Ames-developed health monitoring software application that uses data mining techniques to construct baseline nominal system behavior models by analyzing archived telemetry. IMS then uses these baseline models to identify off-nominal behavior in real-time telemetry, potentially prior to any Caution and Warning (C&W) annunciation for the system. In FY07, Ames delivered IMS-based tools to JSC that allow ADCO mission controllers to monitor ISS control moment gyroscope (CMG) systems in real time. In subsequent years, the IMS CMG tool has been generalized to produce the Anomaly Monitoring Inductive Software System (AMISS) tool for use by any flight control discipline and is now used for real-time flight control room monitoring of 24 ISS subsystems, with additional future deployments planned.
