在捷联式惯导系统中一般采用最少的器件实现惯性制导(陀螺和加速度计各三个),如果其中某一个器件发生故障,系统就失控,所以说可靠性并不是很高的。为提高捷联惯导系统的可靠性,可考虑提高器件本身的可靠性及构成多余度系统,从而增加故障的容许量的两种方式。本文将探讨以冗余度系统来提高系统的可靠性。设为提高可靠性使陀螺的输入轴非直线相交,及为减小制导误差陀螺对直交三轴的影响最小为基本条件,决定最佳配置方案。而冗余度系统是考虑了陀螺故障因素的一种设计方法,
In the strapdown inertial navigation system inertial guidance (gyroscope and accelerometer three) is generally used with a minimum of devices, if one of the devices fails, the system out of control, so the reliability is not very high. In order to improve the reliability of SINS, two ways of increasing the reliability of the device itself and forming the redundancy system to increase the tolerance of the fault may be considered. This article will explore the redundancy system to improve the reliability of the system. To improve the reliability of the gyro input shaft non-linear intersection, and to reduce the guidance error gyro on the orthogonal axis of the minimum conditions for the basic to determine the best configuration. The redundancy system is a design method considering the gyro failure factor,
