Abstract:
In order to study the gyros inflight alignment for guided projectiles,according to principles of the motion about the mass center,the inflight alignment model for projectiles attitude is build up by using the gyros and global positioning system(GPS),which replaces the angle of attack with the dynamic equilibrium angle.The initial values for the pitch angle and yaw angle are calculated.The simulation calculation for one guided projectile is performed based on the compound measurement data.The results indicate that attitude angles of simulation are approximately equal to the theoretical values,and this method can satisfy the requirement of the inflight alignment for the pitch angle and yaw angle.
