摘要

An algorithm for monitoring and diagnosing information failures of gyroscopes and accelerometers of two semianalylic inenial navigation systems (INS) included in the navigation complex (NC) of a submarine has been suggested and is considered in this paper. The NC is supposed to use the information from a water speed log (WSL). The algorithm for monitoring and diagnostics is intended to detect the type of fault (higher zero bias of one of the two "horizontal" accelerometers and higher drift of one of the three gyroscopes that are undelectable by INS monitoring facilities), to estimate its value and determine which of the two INS is faulty. The possibilities to recover the faulty INS are discussed. The simulation data and the results of experimental test of the algorithm are given.
