Abstract:
1. A method for adjusting the flight path of a projectile, comprising: a) Measuring the magnitude and direction of the uttering of a projectile launch tube, at an ejection time of a projectile from said launch tube; b) Measuring a velocity deviation of said projectile from a nominal velocity; c) Measuring an angular deviation of the sight of said launch tube, being equal to the angular deviation between a line coinciding with the direction of gravity and a line passing through the center of the launch tube and the center of the sight; d) Determining a compensating impulse vector to be applied to said projectile during an initial flight path thereof based on the magnitude and direction of said uttering, velocity deviation and angular deflection; and e) Applying said compensating impulse vector to said projectile by activating a flight correction unit, the thrust developed by said flight correction unit adjusts the flight path of said projectile by a magnitude and direction substantially equal to that of said compensating impulse vector.
