摘要：
The initial alignment of fiber optic gyroscope inertial navigation system (LINS) for armored vehicles is studied when disturbance are present, for example when the motor is running on or people are walking on the vehicle. Based on the signal analyses of the LINS inertial instruments, the observation signals were preprocessed by wavelet transform to reduce the interference, and then the Kalman filter algorithm was improved to increase the stability. The experimental results show that this technique effectively increases the alignment accuracy with disturbances.
