A methodology for quantitatively analyzing the reliability of redundant avionics systems, in general, and the dual, separated Redundant Strapdown Inertial Measurement Unit (RSDIMU), in particular, is presented. The RSDIMU is described and a candidate failure detection and isolation system presented. A Markov reliability model is employed. The operational states of the system are defined and the single-step state transition diagrams discussed. Graphical results, showing the impact of major system parameters on the reliability of the RSDIMU system, are presented and discussed. A methodology for quantitatively analyzing the reliability of redundant avionics systems has been presented. A Markov reliability model was developed specifically for the NASA-sponsored RSDIMU and its performance evaluated via this tool to demonstrate the approach employed. The effects of major parameters of the RSDIMU system on reliability were assessed.
