A method and device for supporting the inertial navigation of a missile heading autonomously to a remote target.

摘要

P A method for supporting the inertial navigation of a missile heading autonomously to a distant target using a sensor producing images, grasping the terrain overflown, looking at a finite angle laterally to the aiming direction, delivering field data from which, in comparison with known terrain data, a position of the missile is derived, which position in turn is compared to the position determined by the inertial navigation, and the inertial navigation system is corrected in proportion to this comparison. BR/ A method characterized in that images of the terrain overflown to produce a sequence of images are continuously taken from different positions of the missile by the sensor, producing images, during the movement of the missile over the terrain , these images being stored electronically. / P
