Output-error parameter estimation, normally a postflight batch technique, was applied to solve the data-compatibility problem in real time. Short segments of data were sequentially processed to enable real-time estimation, and variations on the algorithm were used to expedite convergence from arbitrary starting values of the unknown model parameters. The method was applied to flight-test data to correct the data for systematic instrumentation errors. Results showed that the method produced accurate estimates of the data-compatibility correction parameters at a rate of 0.5 Hz. A sensor fault was also introduced into the flight data, and the use of a data-forgetting algorithm showed that the method was capable of quickly adapting to the data in a way that could enable sensor fault detection.
