method and device for the rotational speed of the geschou00dfziellinie to determine a geschou00dfes and steering, in particular of ammunition

摘要

The method involves estimating a rotation speed and incidence of a projectile in a yawing plane by a kalman filter (43) based on measures of rotation speed in a semi-connected mark. A component is estimated by another kalman filter (44) based on a component in the plane from angular difference measured by a deviation indicator, and the estimation carried by the filter (43). Another speed and another incidence of the projectile in a pitching plane are estimated by the filter (43), and another component is estimated by the filter (44) based on a component in the pitching plane. Independent claims are also included for the following: (1) a device for determining rotation speed of a line connecting a projectile to a target (2) a projectile guiding device comprising a device for determining the rotation speed of a line connecting a projectile to a target.
