Reliability Enhancement of the Analog Computer of Gyroscopic Naval Navigation System Using Integration by Field Programmable Analog Arrays
Ali Peiravi

Abstract:
In this study, we present the results of research carried out in order to increase the reliability of the analog computer of a gyroscopic naval navigation system by integration of a collection of the circuits of the analog computer using field programmable analog arrays. The failure rates of the existing analog computer system and its integrated version using an FPAA are computed. The results show a substantial reduction in the failure rate, a considerable increase in the mean time to failure and therefore an improvement in the reliability of the system. It is proposed that the whole gyroscopic navigation system of the naval vessel be integrated as a mixed system using FPAAs and FPGAs. If this work is extended by integrating other parts of the system, there will be a substantial increase in the MTTF of the system and improvement in the reliability of the whole navigation system. The calculations for the mean time to failures were carried out using MIL-HDBK-217F for the Naval Sheltered and the Naval Unsheltered working conditions per the real operating conditions of the system.
