Article Preview

Aiming at the movement characteristics of trajectory correction projectile, the characteristics, installation configuration and error processing algorithm of gyroscope free strapdown equipment were analyzed for gyroscope free strapdown inertial navigation measurement unit(GFSINMU) by utilizing “current” statistical model combined with the outliers processing method. The results showed that the cumulative errors of GFSINMU can be decreased in a certain range by selecting the installation method of accelerometer and utilizing reasonable error analysis method. Thereby, the measurement accuracy of adjusting GFSINMU can be increased, which can adapt to inertial navigation calculation of high dynamic command correction projectile.
