Attitude measuring method adapted to high speed rotary body

The invention is the attitude measurement method for the high-speed revolving solid. It can be proper for the axial high-speed revolving solid. It installs the three accelerometers of Ax, Ay and Az which the gauging spindle is coincidence with the vertical axis, the cross axis and the vertical axis; also it installs two speed gyroscopes of Gy and Gz which the gauging spindle is coincidence with the cross axis and the vertical axis. The assistant accelerometer A'y which the gauging spindle is coincidence with the negative direction of the cross axis is installed in the carrier. The angular velocity Omegax of the high-speed revolving solid vertical axis is computed by the above expression, the next attitude and navigation resolving are finished by the theory and the method in the strapdown inertial navigation equipment.
