Dr. Lilly Spirkovska Presents Anomaly Detection Using IMS at Spaceops 2010

Code TI’s Inductive Monitoring System (IMS) has been demonstrated for anomaly detection of the spacecraft Ground Support Equipment at the Kennedy Space Center (KSC) as part of the Fault Detection, Isolation, and Recovery (FDIR) project. Dr. Lilly Spirkovska presented a description of IMS and results of the KSC demonstration at the SpaceOps 2010 conference. As a result of the presentation, requests were received for IMS licensing from the director of the Ares I First Stage, United Space Alliance; the monitoring and trends analysis lead for the Chandra X-Ray Observatory at the Harvard-Smithsonian Center for Astrophysics; and the avionics system lead project engineer of the Ariane 5 Programme of the European Space Agency (ESA). ARC Technology Transfer is coordinating the licenses.

BACKGROUND: IMS is an Ames-developed health monitoring software application that uses data mining techniques to establish a baseline of normal behavior for the monitored system derived from archived telemetry. IMS then uses that baseline to identify off-normal behavior in real-time telemetry, potentially prior to any caution and warning annunciation for the system. In FY ’07, ARC/TI delivered IMS-based tools to the Johnson Space Center (JSC) that allow Attitude Determination and Control (ADCO) mission controllers to monitor Control Moment Gyroscope (CMG) systems in real time. In subsequent years, the IMS CMG tool has been generalized for use by any flight control discipline and is now used for real-time flight control room monitoring of 19 International Space Station (ISS) subsystems, with additional deployments under consideration. At KSC, IMS was demonstrated for monitoring of shuttle fuel loading (“tanking”) operations. IMS is being considered as a module of the FDIR system for the Launch Control System (LCS) currently under development for next generation launch vehicles.
