Inductive Monitoring System Delivered for Chandra X-Ray Satellite

Code TI’s Inductive Monitoring System (IMS) has been delivered to the Smithsonian Institution’s Astrophysical Observatory High Energy Division based at Harvard University. IMS will be used to monitor and analyze telemetry data from the Chandra X-Ray Observatory satellite. Dr. Scott Wolk, who is responsible for Chandra monitoring and trends analysis, was introduced to IMS by Dr. Lilly Spirkovska’s presentation on the use of IMS in anomaly detection for Kennedy Space Center (KSC) ground support equipment at the 2010 SpaceOps conference. Dr. Wolk immediately recognized the potential applications for Chandra and requested a copy of the IMS software. The ARC Technology Partnerships Division arranged a software usage agreement with the Harvard-Smithsonian Center for the core IMS software. There are plans to transfer the IMS graphical user interface and additional data analysis utilities currently under development for Johnson Space Center (JSC) International Space Station (ISS) Mission Control applications when they are available.

BACKGROUND: The Inductive Monitoring System is an Ames-developed health monitoring software application that uses data mining techniques to establish a baseline of normal behavior for a 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 JSC that allow Attitude Determination and Control Officers (ADCO) in Mission Control 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 ISS subsystems and has additional deployments under consideration. At KSC, IMS was demonstrated for monitoring of shuttle fuel loading (“tanking”) operations. IMS is also being considered as a module of the Fault Detection, Isolation, and Recovery (FDIR) system for the Launch Control System (LCS) currently under development for next generation launch vehicles.

PROGRAM FUNDING: ARC/JSC Intercenter Task Agreement, supported by SSP; and JSC MER, with KSC work supported by ETDP.
