METHOD FOR FIRING BY GUIDED MISSILE AND MISSILE GUIDANCE SYSTEM Russian patent published in 2003 - IPC

FIELD: methods for firing by guided missiles and optical sighting devices of self-propelled missile guidance systems. SUBSTANCE: in using the method for firing by a guided missile with on optical communication line with the ground control system including the operations of missile launching and control of it during flight from the ground equipment, alignment of the launcher axis with the sight optical axis is preliminarily performed, alignment is performed in two stages. First alignment of the axes is carried out, the aligned position of the axes is fixed and the error signals are read off, the error signals in the aligned position are memorized, then in the process of service of the control system the operation of alignment is repeated, at a repeated alignment the conformity of the obtained error signals with the error signals corresponding to the memorized ones at the first alignment, and in case of a misalignment of the mentioned error signals, corrections depending on the angles of deviation of the axes in the initially aligned position and misalignment obtained at the repeated alignment are introduced in the error signals at firing. The repeated alignment is preferably performed systematically with a preset periodicity. After a repeated alignment the range to the target is measured and the direction of the launcher axis is set in accordance with the functional dependence from the measured range and corrections introduced after the repeated alignment taken into account. After the performed operations a fire is shot. The method is realized with the aid of the missile guidance system containing the guided missile, launching system with the missile type driver and the optical sight included in the composition of the launcher. The system is featured by the fact that it contains a device for optical communication of the launcher with the sight provided with a turning gear, and a launcher guidance drive with a launcher axis position pickup connected to the control bus, connected to which are also the launching system, optical sight and the launching control processor introduced in the system. EFFECT: enhanced accuracy and reliability of the armament complex. 5 cl, 3 dwg
