A method for calibration of fiber optical gyroscope(FOG) strapdown inertial navigation pose system by single-axis rate turntable is studied,aiming at problem of traditional calibration method high-cost of calibration and strict with north reference. Establish error model,fix the system on single-axis turntable to make sure that the three axises are down in turn. The twelve parameters consists of zeros bias scale factor and mounting misalignment angles are calibrated. Through analysis on calibration precisio...
