Abstract

Aiming at the problem that the airborne inertial guidance system needs to be electrically aligned to identify the initial attitude angle of the guided gun after ejecting the bore, a method of aerial alignment of guided projectiles based on INS (Inertial Navigation System)/radar command combination is proposed. Based on the kinematic equation of the projectile's rotation around the center of mass, the aerial rough alignment and precision alignment models of guided projectile attitude were established, and finally the low-speed roll-guided projectile was used as the research object for simulation verification. The simulation results show that the aerial alignment method of guided projectiles used in this paper can effectively identify the attitude angle of the projectile body when flying in the air, and meet the accuracy requirements of guided projectile attitude estimation
