Optimal platform skewing for Space Shuttle inertial measurement unit redundancy managementConstraints are applied to a general quaternion which describes the skewing between platforms of the Space Shuttle IMU. Once a skewing is derived, the use of the failure magnitude to threshold ratio makes possible predictions of the identification sensitivities for various failure modes. This in turn simplifies analyses and identifies portions of the flight envelope where second failure coverage is lacking. The square root of 6 and square root of 2 skewings have been baselined for use during nominal entry; the realignment software will be used on orbit to reskew the IMUs to the optimal configuration.
