US12435951 - Sight

An apparatus for providing information for adjusting a sight of a projectile weapon is provided. The apparatus comprises an input for receiving information regarding measured velocity of a projectile in flight at least at one moment of time. The apparatus comprises an analyzer for determining the velocity and moment of time; an estimator for estimating value for a set of parameters; a calculator for using velocity, moment of time, estimated value and a zero-in angle of the sight to calculate a velocity of the projectile at the moment of time; and a comparator for comparing calculated velocity and measured velocity to determine whether a difference between the calculated and the measured velocity is less than a predetermined value. The apparatus is configured to repeat estimating, calculation of the velocity of the projectile and comparison with another estimated value for the set of parameters to model a trajectory of the projectile.
