Based on launcher's cradle, a calibration method was proposed about strapdown inertial measurement unit (SIMU) in vehicular missile. Within the limit of cradle's rotational degree, and small roll of launch vehicle was introduced, 5-position was used for realization of IMU error parameters identification, and modular square approximation was used to improve calibration factor to ensure their accuracy. The experimental result shows that the improved calibration method provides a safe and reliable way for field IMU's daily maintenance, meanwhile, calibration precision is ensured and dependence on high precision calibration turntable is reduced.
