| Abstract |
In this paper, we propose an initial alignment method of SINS(slave inertial navigation system) suitable for a rotorcraft using an adaptive notch filter. In the proposed method, adaptive notch filter is applied to eliminate the alignment error caused by the rotor vibration of the aircraft, We verify the performance improvement of the proposed alignment scheme comparing with the conventional transfer alignment method by rotorcraft test. The test result shows that the proposed alignment technique has improved alignment performance. |
