METHOD OF LAUNCHING LASER BEAM-GUIDED ROCKET Russian patent published in 2014 - IPC F41G7/26 

FIELD: weapons and ammunition.

SUBSTANCE: proposed method comprises target ranging and input of measured magnitude to surface control system. Beam axis initial elevation Y₀ is set relative to target point direction to launch the guided missile. Beam axis maximum elevation Y_max is set relative to target point direction. Missile flies at maximum elevation till the time set at surface control system in compliance with measured range to target, beam axis being aligned with target point direction. Note here that the elevation is serially changed in time interval from rocket launch moment to moment $$t_1=\frac{\mathrm{2,5}\dots \mathrm{3,5}}{{\omega }_{cut-off}},$$ where ω_cut-off is missile control system frequency cut-off, rad/s while initial elevation Y₀ is kept variable. Note here that its magnitude is set by relationship $$Y_0=Y_{\min }^p+\left(\mathrm{0,5}÷\mathrm{1,0}\right)R_b,$$ where $$Y_{\min }^p$$ is minimum possible vertical deviation of the missile from target point direction at this flight path section, m; R_b is beam radius, m, while during period from moment t₁ to moment $$t_2=t_1+\frac{Y_{\max }-Y_0}{V_e},$$ where V_e is the maximum tolerable beam elevation rate, m/s, elevation is increased to Y_max.

EFFECT: higher accuracy of fire.
