Fault diagnosis is necessary in inertial navigation system to ensure navigation success. The kernel principal component analysis (KPCA) method is applied to fault diagnosis of inertial navigation system. At first, the square prediction error is used as the fault monitoring indictor. In addition, this paper locates the faults by using sensor variables changes. In order to reduce the dependence to the prior knowledge in selecting kernel function parameter, genetic algorithm is introduced into the Gauss RBF kernel function parameter optimization. It can improve the scientific nature of parameter choice. Experimental results show that the method based on KPCA of the inertial navigation system has good fault monitoring and recognition ability. © Springer-Verlag Berlin Heidelberg 2014.
