Note (General): This report describes an efficient method for increasing the reliability of a strapdown inertial navigator,i.e.,if redundant sensor arrays and additional sensors are employed,and if properly oriented,they serve to increase the accuracy of the system.The reliability and accuracy of various redundant systems using four-,five-and six-sensor arrays are analysed.It was found that models of non-orthogonal orientation have higher reliability than those of orthogonal orientation using the same number of sensors.Therefore the former models were used as models of redundant sensor arrays,and accuracy analyses were made only on those.In these analyses,the minimizing function of the influence of sensor errors on the system was used as a criterion,and optimum solutions were obtained in each system.The solutions,which are a standard of the optimum sensor array,did not vary after one or more sensors had failed and had been removed from operation.The improvement of accuracy was 13.4％,22.5％ and 29.3％ for four-,five-andensor systems in comparison with conventional three-sensor array when all sensors were normally operating in each system.
