REDUNDANCY MANAGEMENT OF MULTIPLE INERTIAL SYSTEMS FOR SPACE SHUTTLE.

Failure detection and isolation techniques are developed for application to ″off-the-shelf″ type four-gimbaled inertial measurement units such as the KT-70 or Carousel IV. The adequacy of ″off-the-shelf″ systems for both attitude and velocity detection methods is evaluated with emphasis on realizable redundancy management techniques using ″off-the-shelf″ IMU technology in shuttle trajectory simulations.
