Abstract
The Angle Data System of the 64-m-diameter antenna utilizes two-axis autocollimators as the optical link between the precision instrument mount and the intermediate reference optical assembly. The accuracy, resolution and stability of these instruments directly affects the pointing accuracy of the antennas. With an accuracy and resolution of better than one arc second, great care must be taken in each phase of the design and construction.
