Abstract
The presently disclosed subject matter includes a method, apparatus and computer storage device for reducing dispersion of a rocket caused by jet-stream misalignment, the rocket comprising a rocket engine. Information indicative of a division of total operation time of the rocket engine into a first time period and a second time period is obtained; wherein an impulse which is generated during the first time period is at least approximately the same as an impulse generated during the second time period; a period of time which equals to the first time period starting from time of activation of the rocket engine is measured; upon termination of the period of time, the rocket is rotated around the rocket's longitudinal axis; and the angle of rotation measured; and the rotation is stopped once a 180° rotation is completed.
