GUIDED MISSILE GUIDANCE SYSTEM Russian patent published in 2004 - IPC

FIELD: armament, in particular, artillery guided missiles with a laser homing head. SUBSTANCE: the guided missile guidance system has a control actuator, inertial gyroscope, function selector switch and a homing head, including the functional element, such as an OR gate forming at its output the signals of the photodetector device, the "LOCK-ON" output of the homing head is connected to the first input of the first AND gate and via an inverter - to the first input of the second AND gate, whose second inputs are connected to the second and third outputs of the inertial gyroscope, the output of the first AND gate is connected to the "Compensation" input of the homing head and to the third input of the first OR gate, whose second input is connected to the first output of the inertial gyroscope, and its output - to the input of the first power amplifier, the output of the second AND gate is connected to the input of the second OR gate, whose output is connected to the input of the second power amplifier, the "+Z" and "-Z" outputs of the homing head are connected to the first inputs of the third and fourth AND gates respectively, the outputs of the third and fourth AND gates 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, and the second inputs of the control windings, the input of the inertial gyroscope and the input of the function selector switch are connected to the power source of the on-board equipment, inserted are the first and second single-shot multivibrators, the fifth and sixth AND gates, the third OR gate. The output of the OR gate of the homing head is connected to the input of the first single-shot multivibrator, whose output is connected to the input of the second single-shot multivibrator, whose output is connected to the first input of the third OR gate, whose second input is connected to the output of the function selector switch. The output of the third OR gate is connected to the second inputs of the third, fourth, fifth and sixth AND gates, the first inputs of the fifth and sixth AND gates, the first inputs of the fifth and sixth AND gates are connected to the "-Y", "+Y" outputs of the homing head respectively. The outputs of the fifth and sixth AND gates are connected to the first inputs of the first and second OR gates respectively. EFFECT: enhanced accuracy of guidance. 2 dwg
