This paper studied systematic calibration technique of the Laser gyro SINS based on dual-axis turntable. A calibration model of gyro and accelerometer was established with constraints a 30 dimensional Kalman filter calibration model was derived from SINS error equation. After a dual-axis position rotate route was designed, energized and identified the inertial instrument calibration parameters using speed and position as observation. Simulation results show that this method can accurately estimate 15 calibration error parameters for the gyro and accelerometer, has a certain reference value.
