rate aiding tracking prevents or dampens the effect of large scale target tion on a missile borne tracker during transition of a missile from prelaunch tracking to post launch tracking . rate aided tracking includes a feedback network responsive to existing stable platforms for combining a tracker output signal with a rate signal that is itself responsive to torques present on a stable platform due to target sensor motion . the feedback network includes an integrator and a transformation circuit and is active only during the missile launching phase of operation when transient effects are manifest .
