Abstract

Methods and systems for trajectory correction of a projectile or a munition during flight. The projectile comprises a force generator disposed on a module rotatable around the projectile's longitudinal axis, to generate a force in a direction to correct the trajectory of the projectile. The force generator may have a nozzle, adapted to expel a jet of gas in the desired direction, and a valve for controlling the duration of the expulsion. Guidance of the projectile may be achieved by defining the position of the target on a camera array using a telescopic sight, and detecting an optical signal emitted by an encoded light source, mounted on the projectile, and determining its position in the camera array. Determination of the range of the projectile then enables calculation of the actual trajectory, and if necessary, optically encoded correction signals are sent to the projectile for appropriate trajectory correction.
