Title: Model-Based Real Time Assessment of Capability Left for Spacecraft Under Failure Mode
Agency: NASA
Contract: NNJ06JD76C
Award Amount: $69,872.00


The proposed project is aimed at developing a model based diagnostics system for spacecraft that will allow real time assessment of its state, while it is impacted by a failure mode, and provide to the crew the possible reconfiguration strategies to continue the mission. While a lot of research is being done on the development of Integrated Vehicle Health Management (IVHM) system, very little effort is made to provide the spacecraft with the capability to use IVHM information in order to assess the possible strategies possible when a failure event has impacted the vehicle. A model based system can use its understanding of the system state to deduce the potential reconfiguration commands and optimize the outcome in order to preserve the mission goals.Our proposed project is targeted at supporting the spacecraft fault tolerance capability by searching the system states space and selecting the most appropriate sequence of actions to execute in order to optimize the possibility of mission success, by reconfiguring the spacecraft to a desired new state.
