With the development of strapdown inertial navigation system
the demand for the precision and speediness of inertial navigation is becoming higher and higher.The speediness depends on the initial alignment time.Compared with the restricted traditional initial alignment
transferring alignment is a new kind of quick initial alignment method.The velocity matching transfer alignment method is analyzed.The principle of the lever-arm effect is derived on this basis.The simulation result shows that the stable yaw misalignment angle is-0.5°.The experiment shows that pitch misalignment angle is-0.22°;roll misalignment angle is-0.37°;yaw misalignment angle is-0.35°.So the influence of the lever-arm effect error on misalignment angle is verified.
