Abstract: An alignment device mounts to a missile system such that the view of a missile seeker is limited to limited fields of view at predetermined positions relative to a known reference such as the missile centerline. Once the alignment device is mounted to the missile system, an energy source emitting energy viewable by the seeker is located within a field of view. Once the seeker has locked-on to the energy source in a limited field of view, the pointing angle of the seeker can be observed by a measurement device communicating with the missile controller. Any pointing angle observed by the measurement device which differs from the known position defined by the alignment device, represents a displacement error of the seeker. Appropriate compensation is then applied to the missile controller such that alignment errors are accounted for.
