    Abstract
  • The loop characteristic of close-loop interferometer fiber optic gyroscope(I-FOG) was studied first and its self-diagnosing capability has been reveal. A new type FOG with self-diagnosability has been gotten and used in a redundant strapdown inertial measure unit (RSDIMU), and a new fail tolerance algorithm has been designed for this unit too. In this algorithm, both the output and the state information of this FOG were induced, so that the information redundancy at the instrument grade has been realized and the fail tolerance capability was improved from fail operate(FO)-fail operate(FO)-fail safe(FS) to FO-FO-FO-FO-FS. Using Markov reliability evaluation mode, the reliability was calculated, compared with the old system, the reliability was improved greatly.
