| 内容記述 | This report describes an efficient method of increasing the reliability of a strapdown inertial navigator by use of a redundant sensor system. It also describes a preliminary technique to detect and isolate the sensor failures, and how to determine the tolerance limits of the detection delay. The reliability and the accuracy of various redundant systems using four-, five-, and six-sensor arrays are analyzed. It was found that models of non-orthogonal orientation have higher reliability than those of orthogonal orientation using the same number of sensors. If the sensor arrays are optimum, the improvement of accuracy was found to be 13.4％, 22.5％, and 29.3％ for four-, five-, and six-sensor systems in comparison with conventional three-sensor arrays when all sensors are operating normally. A trial to detect a sensor failure and to find a way to compensate for performance degradation of a system is done by using a set of parity equations. And the system is a six-sensor array made up with DRMIG. In this trial, the method one of substituting the integrated values of the sensor data into those equations in order that the detection performance be better. The detection delay is evaluated as a quantitative relation to the navigational error on the assumption that a redundant system is employed for a mission. Finally, we may conclude that fundamental concepts about the optimum sensor array and failure detection, and their application to a mission, were established in this paper. | |||||||||
