The aspect system for the HEAO-B Observatory provides the necessary absolute referencing of the Observatory coordinates to the celestial sphere with a precision of one arc second. In addition, it provides realtime data to the Spacecraft to permit pointing of the Observatory to one arc minute. The system is composed of three star trackers with associated shades, a pair of bright object detectors and a fiducial light system for referencing the experiment X-ray axis to the star tracker axes.
