Abstract
In a system including a launcher device and a projectile of the type that spins in flight, an assembly for detecting and correcting deviations of the projectile from the planned flight trajectory of the spinning projectile, leading from the launcher device to a selected, visible target, including, in combination: PA1 a first electric signal generator associated with the launcher device; PA1 target marker including a light emitter and being associated with the launcher; PA1 a sensor device mounted on the projectile and spinning together with it, including sensor having a forehead and an optical assembly capable of focusing and projecting on said forehead a beam of light reflected from the target so as to draw on the forehead an imaginary circle whose radius is proportional to a real-time deviation angle defined, in a first approximation, as the angle between the tangent to the projectile's flight trajectory and the projectile's line of sight (LOS) towards the target; and PA1 a thruster initiator that is capable of activating thruster device(s) in the case that the imaginary circle radius exceeds a pre-determined value that corresponds to a predetermined largest permissible deviation…
