Abstract
In the precision-pointing mode the 70-meter antennas utilize an optical link provided by an autocollimator. In an effort to improve reliability and performance, commercial instruments have been evaluated as replacement candidates, and upgraded versions of the existing instruments have been designed and tested. The latter have been selected for the Neptune encounter, but commercial instruments with digital output show promise of significant performance improvement for the post-encounter period.
