成果简介	NOVELTY - The method involves using signals from the DUS and DLU. The signals are converted using quaternions into the corresponding roll and pitch angles, and the output signals of the vertical gyro, roll and pitch are jointly processed with signals corresponding to the linear accelerations obtained by conversion. The flight parameters of the aircraft are taken into account. The signals from the DLU are additionally used for an approximate estimate of the roll angles and pitch. The calculation of the quaternion q orientations for forming roll angles and pitch is performed, and the simplified estimates of the roll and pitch are taken into account. The joint processing of roll estimates and pitch is carried out. The roll estimate is determined. The features of the influence of aircraft dynamics processes on accuracy are taken into account, and the orientation quaternion is updated in accordance with the roll and pitch estimates. USE - Method for correcting backup vertical gyro of aircraft.
