ABSTRACT:
The present invention concerns using star sightings to supplement the ineal instruments in nonfixed launch systems so as to provide increased accuracy without refinement of the inertial systems. It is particularly applicable to a system in which the missile is launched from a moving base of uncertain position. A stellar fix is obtained by pointing a sensor in the direction of a star, scanning the optical field of view through an elongated slit which is parallel to the pitch axis and centered along the missile roll axis, rotating the missile 90.degree. to interchange the pitch and roll axes and scanning again to establish another coordinate on the first star sighted and a single coordinate on a second star.
