A systematic reliability analysis procedure for evaluating fault-tolerant inertial measurement unit (IMU) architectures is described. This reliability analysis procedure is based on modeling the system architecture, the component reliabilities, and the redundancy management. The component reliabilities are based on constant failure rates and exponential failure distributions. The procedure computes both the overall reliability of the IMU and the major contributors to the IMU reliability. This reliability analysis procedure is used to evaluate and compare three state-of-the-art fault-tolerant IMU architectures: the triple triad architecture, the dual quad architecture, and the hexad architecture.
