Abstract
Initial alignment is a prerequisite for the work of INS and integrated navigation system. In order to solve the problem of rapid alignment of guided projectiles under high dynamic conditions, this paper proposes an air coarse alignment method based on kinematics constraints, and compensate for the influence of the earth’s rotation. At the same time, this paper increases the pitch and yaw angle measurement information in the fine alignment process, thereby improving the speed and accuracy of air fine alignment. Simulation experiments show that after compensating for the influence of the earth’s rotation, the roll angle alignment error is reduced by 1°. Compared with the traditional speed + position six-dimensional measurement fine alignment method, after adding pitch and yaw angle measurement information, The eastward speed error is reduced by 0.044 m/s, the northward speed error is reduced by 0.156 m/s, the sky speed error is reduced by 0.126 m/s, the eastward misalignment angle error is reduced by 2.1°, and the northward misalignment angle error is reduced by 0.7°, and the sky misalignment angle error is reduced by 0.86°.
