Abstract

This article describes the new 34-m high efficiency Azimuth — Elevation antenna configuration, including its features, dynamic characteristics and performance at 8.4-GHz frequencies. The current-technology features of this antenna produce a highly reliable configuration by incorporation of a main wheel and track azimuth support, central pintle pivot bearing, close tolerance surface panels and all-welded construction. Also described are basic drive controls that, as slaved to three automatic microprocessors, provide accurate and safe control of the antenna’s steering tasks. ; At this time antenna installations have been completed at Goldstone and Canberra and have operationally supported the Voyager — Uranus encounter. A third installation is being constructed currently in Madrid and is scheduled for completion in late 1986.
