Automated Fault Diagnostics, Prognostics, and Recovery in Spacecraft Power Systems, Phase I

Completed Technology Project

Project Introduction

Automated Fault Diagnostics, Prognostics, and Recovery in Spacecraft Power Systems, Phase I
Constellation Program, the next frontier of NASA's space exploration plan, targets for manned mission to Moon and Mars. The missions under this program will be of long-duration and far more critical than any previous manned mission. Integrated Systems Health Management (ISHM), which includes fault detection, diagnosis, and prognosis, has been recognized as one of the critical processes that will enhance system functionality, mission success probability and crew safety for these missions. In addition, ISHM should support in deciding reactionary actions in response to a system failure or a failure precursor, i.e., the system recovery functions. Spacecrafts for the constellation program requires a significant degree of autonomy that includes the ability to monitor their own health and perform mission objectives in the wake of unexpected events (faults, failures, etc). In response to the needs stated in the solicitation topic x2.01, Qualtech Systems, Inc. (QSI) proposes to develop novel diagnostic, prognostic, degradation analysis and automated recovery techniques for spacecraft power systems. The proposed effort will use reactive mission planner technologies for formulating recovery options and mission re-planning to accommodate for degradation in power systems. Inclusion of the resulting technologies will streamline cost of long-duration space missions and enhance the mission success probabilities. More »
