I 1 MARINER/MARS 71 PROGRAMMERS AND FORMATTERS ........... 7-IZ8 V SECTION I INTRODUCTION In recent months, much emphasis has been placed within the NASA, other Government agencies, and industry to use "off- the-shelf" hardware elements in new and advanced astrionics system designs. This cost effective approach has as its goal the reduction of R&D and testing costs through the application of proven and tested astrionics components. The ready availa- bility to the designer of data facts for applicable system components is highly desirable. The Astrionics System Designers Handbook has as its objective this documenting of data facts to serve the anticipated requirements of the astrionics system designer. Eleven NASA programs were selected as the reference base for the document.
