ABSTRACT:
The present invention relates to a system for guiding a missile in alignment onto a moving target. In particular, the guidance computer of the system has a first unit for estimating the state of the missile and the movements of a target on the basis of the measurement of the position of the missile with respect to a datum axis, obtained by angular deviation measuring means, and by using a model of the dynamic behavior of the missile as well as kinematic model of the target. Additionally, the guidance computer has a second unit linked to the first unit for deriving tracking orders and datum values for slaving the missile, and a third unit linked to the first and second units for deriving the control order applied to the missile and the first unit.
