Correlation Signal Processing and Structural-Parametric Identification of a Dynamic Error Model of a Wave Solid-State Gyro

The technology of structural-parametric identification of dynamic error models of sensors of inertial navigation systems is considered. This technology is based on the calculation of the correlation function for sensor errors estimates and its use to determine drift and diffusion coefficients. The identification results are presented for the wave solid-state gyro (WSSG) error model. The influence of the inaccuracy of setting the parameters in the WSSG drift model on the accuracy characteristics of the inertial attitude and heading reference system is shown.
