摘要：

A dynamic calibration method for the lever-arm effect of the Strap-Down Inertial Navigation System (SINS) on hypersonic cruise vehicles is proposed. The lever-arm length is extended as the state variables of the Kalman filter; the model of the lever-arm effect is built, and observability is analyzed. Simulation results show that the proposed method can effectively calibrate the lever-arm length. The calibration results are utilized to compensate the lever-arm effect, and the accuracy of SINS is improved.
