ABSTRACT:
A system and apparatus for accurate measurement of a rocket's attitude that includes a laser source placed downrange and pointed towards the rocket with a diverging beam. The beam will be intercepted by a mirror on the rocket's ogive, and the reflected beam will then be presented on a vertical target. A detector assembly positioned behind the vertical target plane detects the centroid of the reflected energy and provides an analog output signal.
