METHOD OF DETERMINING ANGLE OF BANK OF MISSILE REGULARLY SPINNING IN ROLL AND DEVICE TO THIS END Russian patent published in 2013 - IPC F41G7/00 

FIELD: weapons and ammunition.

SUBSTANCE: prior to launching, missile initial roll φ₀ is measured or preset to memorise the signal corresponding thereto to start integration of missile spin rate signal. Integrator is set to zero on reaching integrated magnitude of signal corresponding to missile roll equal to 360°. Thereafter, integration is reiterated to use additional Earth magnetic field transducer, its signal being converted in rectangular oscillations of angular interval of 360 degrees, and to generate, at preset time moment, the signal enabling passage of rectangular oscillation fall and rise fronts. With first said rise of fall front passage, integrated signal magnitude A₁ corresponding to missile roll angle φ₁ is measured. In case relationship φ_max>φ>φ_min is satisfied, magnitude A₁ corresponding to φ₁ is memorised where φ_max and φ_min are maximum and minimum design roll angles, respectively.

EFFECT: higher accuracy.
