Abstract

The paper outlines the method for calibration of a strapdown inertial measurement unit (SIMU) based on fiber-optic gyros (FOG) in dynamic conditions on a test bed. Calculated components of linear velocity vector and position of SIMU accelerometer unit on the test bed platform are used as a reference. The accuracy of a proposed method is estimated by testing the SIMU based on FOGs by IXSEA (France) on three-axis rate table by Acutronic.
