An active damping method and a self-contained active damping system that can be retrofitted to existing rockets are provided which for reducing the dispersion of rockets by using lateral thrusters to oppose any initial yawing motion. The self-contained system of the present invention can be installed in a cylindrical section of a rocket body by insertion between other flight body parts.

1. A method for reducing dispersion of a missile launched into a trajectory toward a desired target, said launched missile having an initial yawing rate, at least one preset threshold condition for said initial yawing rate, and at least one lateral thruster, said method comprising the steps of:(a) launching the missile into said trajectory; (b) measuring the launched missile's initial yawing rate; (c) determining if said measured yawing rate exceeds said preset threshold condition; (d) selecting a lateral thruster to oppose the measured yawing rate; (e) firing the selected lateral thruster; and (f) repeating steps (b)-(e) for a preset period immediately after launch.
