1. An apparatus for providing information for adjusting a sight of a projectile weapon, the apparatus comprising:
an input for receiving information regarding a measured velocity of a projectile in flight at least at one moment of time, which projectile has been fired from a projectile weapon;
an analyzer for determining the measured velocity and the moment of time;
an estimator for estimating a value for a set of parameters;
a calculator for using the measured velocity, the moment of time, the 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 the calculated velocity and the measured velocity to determine whether a difference between the calculated velocity and the measured velocity is less than a predetermined value;
wherein the apparatus is configured to repeat the estimating, the calculation of the velocity of the projectile and the comparison with another estimated value for the set of parameters to model a trajectory of the projectile.
