A system for controlling the trajectory of a launched projectile. More particularly, a method for correcting the projectile jump displacement of a launched projectile after it is released from a vessel using on-board G-hardened accelerometers orthogonally mounted along the longitudinal axis of the projectile. Deviation from an intended flight path is corrected by firing selected trajectory diverting thrusters mounted around the periphery of the projectile. Eliminating or reducing projectile jump, or the angular deviation of the flight path of a projectile relative to its intended trajectory, will greatly increase the accuracy of gun fired projectiles.
