METHOD OF GUIDANCE OF SPINNING MISSILE WITH RELAY DRIVE OF STEERING BODY AND SYSTEM OF ITS IMPLEMENTATION Russian patent published in 2014 - IPC F41G7/00 

FIELD: instrument.

SUBSTANCE: point of time t_s is set before launching, and the relay two-position signal V is formed by the law $$V=\{\begin{array}{l}sign\lfloor h_y+U_1\rfloor C\left(\gamma \right)+sign\left[h_z+U_2\right]S\left(\gamma \right)att\le t_0\\ sign\lfloor h_y+U_1\rfloor C\left(\gamma \right)+sign\left[h_z+U_{2}sign(-U_1)\right]S\left(\gamma \right)att>t_0\end{array},$$ where U₁, U₂ are the signals periodic by the angle γ, which are shifted by the angle π/2 relative to each other and by the angle π/2, respectively, relative to the signals C(γ), S(γ), and the point of time t₀ is determined as the nearest point of time after the point of time t_s set before launching, corresponding to switching the signal S(γ) from zero level to the positive level. At that in the system with relay drive of steering bodies the corresponding additional summing amplifiers, relay elements, modulators, phase shifter and an inverting amplifier are added.

EFFECT: improving accuracy of guidance of the missiles with relay drives of steering bodies.
