Abstract

The missile-based redundant SINS (strap-down inertial navigation system) output the measurement data by using pulse quantization. Pulse quantization can disorganize the errors in the original measurement signal, cause an instantaneous drift of 50 degree/hour, and thus brings about great difficulty to the process of fault diagnosis. Focusing on the problem that the pulse quantization results in difficulty to the fault diagnosis of the redundant SINS, this paper proposes a method that using a low pass filter reduces the quantization noise. Based on GLT (generalized likelihood test) method, one of the methods used for fault diagnosis of the redundant SINS and combined with a low pass filter, this paper studies the effects before and after the fault diagnosis comparatively and draws a conclusion that a low pass filter is helpful for improving the effect of quantitative fault diagnosis. The result of the simulation experiment shows that the effect of the fault diagnosis after improving is close to that before using pulse quantization, and that the effect can detect the order of 5 degree / hour accurately.
