Health Management Processes• Health Management is an expert-intensive process

- Large Mission Control Center- Labor-intensive ground operations- Intensive training of flight crew and mission support teams

• Goals of ISHM Systems- to detect and understand critical failures early enough to

respond and avoid the most serious consequences- to reduce the activity required of Mission Control Center- to reduce the vehicle house-keeping by flight crews- to reduce the amount of training- to streamline the ground processing

• ISHM systems enable more efficient decision processes- Reduce dependency on Earth-based teams- response to malfunctions- mitigating the impacts of failures on the mission- planning and scheduling systems- efficient ground operations

Health Management Technology – spiral 1

• Intelligent C&W• Flight-critical failure detection and annunciation• Fast real-time detection and diagnosis• Deterministic diagnosis• Probabilistic analysis and prognosis• Updatable and reconfigurable detection, diagnosis

and prognosis• System of systems architectures to manage health

consistently across the program

System Health State information is vital for keeping the crews safe and programs affordable as the US reaches for sustainable, long-term exploration of space

Health State for Space Exploration

• Based on the stakeholders’ needs• Take advantage of technological advances• Balance technology with human skills• Establish clear goals for

- More efficient operations- Higher quality of information

Health management in the right amount is required to meet program safety and efficiency needs for sustaining space exploration

Significance

• Root-cause diagnostics- accomplished using existing sensor and C&W messages- fits well with current sensors, procedures and protocols- significant time in both training for and handling actual

malfunctions can be saved for controllers and crew

• Procedure management- select existing procedure based on diagnostic results

• Prognostic applications- Prognostic/projective techniques can be applied to complex

situations to improve situational awareness

• Technical challenges addressed- loss of comm (including spurious and erratic data)- temporal effects (multi-rate telemetry)

ISHM Activity ModelActivities are performed to identify, mitigate and resolve system faults...

• Health State DeterminationMonitor, detect, and isolate faults to identify root-cause failures with diagnostics and prognostics

• MitigationAssess impact of failures and mitigateto minimize impact to mission.

• RepairPerform activities to repair failed component and return system to nominal state.

• VerificationPerform activities to verify that repair effectively returns system to nominal state.
