  • Fault-tolerant system, apparatus and method
    Publication number: 20060074558
    Abstract: A method, apparatus and system are described having a minimum variance estimator of state estimates typically in navigation embodiments where a sensor and/or effecter fault detecting module is adapted to execute residual testing steps using the Multiple Hypothesis Wald Sequential Probability Ratio test, the Multiple Hypothesis Shiryayev Sequential Probability Ratio test, the Chi-Square test and combinations thereof to determine the likelihood of sensor and/or actuator fault occurrences and thereafter isolate the effects of the one or more identified fault from the state estimates.
    Type: Application
    Filed: November 9, 2005
    Publication date: April 6, 2006
    Inventors: Walton Williamson, Jason Speyer
