Method of piloting and/or guiding a projectile and piloting and/or guiding device implementing such a method

摘要

The method involves implementing a target detector that allows to locate a target (13) in a reference location related to a projectile (1). Components of a line of sight vector between the target and the projectile are deduced using aiming algorithms. Three components of a terrestrial magnetic field are measured in the reference location. Rotation speed of the projectile around roll, pitch and yaw axes is determined by combining two pseudo-gyrometric evaluations that are based on vector and magnetic field components. An independent claim is also included for a device for terminal piloting and/or guiding of a projectile toward a target.
