DSN automation

An overall hierarchical automation philosophy along with the results of the radio frequencies automation effort undertaken 2 years ago are summarized. A brief description of each subassembly controller's salient features, the software development process, and the common software used by these controllers will be presented. Comments will be made with respect to the relative advantages of high-level language and assembly language, the operational effectiveness of operator Macro commands, and the program development, and a list of suggested future effort will be given.
