MISSILE GUIDANCE SYSTEM Russian patent published in 2003 - IPC

FIELD: armament, in particular, artillery guided missiles with a laser homing head. SUBSTANCE: the missile guidance system has a control actuator, inertial gyroscope and a homing head, whose "Lock ON" output is connected to the first input of the first AND gate, whose second input is connected to the output of the inertial gyroscope. The output of the first AND gate is connected to the "compensation" input of the homing head and to the second input of the OR gate, whose first input is connected to the "-Y" output of the homing head, and its output is connected to the second input of the second AND gate. The "+Y" output of the homing head is connected to the first input of the third AND gate and via the first inverter - to the first input of the second AND gate. The output of the second inverter is connected to the second input of the third AND gate. The outputs of the second and third AND gates are connected respectively to the inputs of the first and second power amplifiers, the "Z" and "-Z" outputs of the homing head are connected to the inputs of the third and fourth power amplifiers respectively. The outputs of the first, second, third and fourth power amplifiers are connected to the first inputs of the first, second, third and fourth control windings of the control actuator respectively, whose second inputs are connected to the power source of the missile-borne equipment. A fourth AND gate, is used, whose first input is connected to the "Prohibition" output of the homing head, its second input is connected to the output of the OR gate, and its output is connected to the input of the second inverter. A shutter is installed in the gyroscope, light-emitting diode and a photodiode with formation of an optron coupling between them, the shutter is installed for rotation at the speed of the missile spinning and periodic closure of the light flux between the light-emitting diode and photodiode, the photodiode serves as the output of the gyroscope. EFFECT: enhanced accuracy of guidance. 1 dwg
