This report presents the results of the "Application of Advanced Technol­ ogy to Space Automation Study," which was performed under Contract NASW­ 3106. A synopsis of specific technology areas is provided alongwith an analysis of the role of automation in the space program. It also summar­ izes the benefits to be derived from automation and provides a discussion on the required technology efforts that should be directed toward obtain­ ing these benefits. Furthermore, presentation of a logical approach di­ rected toward achievement of the desired automation goals is provided for future NASA 'pace missions.. It is intended that this report be updated and expanded at periodic in­ tervals so that a current summary of the respective technology areas be available as required for new initiatives or technology prediction exer­ cises. More concise summary techniques are being developed and will be incorporated in the future. However, in the interest of time and avail­ able funds, this issue has been published as a first step toward achieve­ ment of a technology summary. The primary contributors and their respective areas of research are as follows: Study program manager - Roger T. Schappell; Electronics - John T. Polhemus; Information gathering - John T. Polhemus; Image data processing - Chieng-Y Chang; Ground support systems - Catherine A. Hughes; Rendezvous, stationkeeping, and docking - Roger T. Schappell; Fault tolerant processors - James R. Stephens; Autonomous navigation - James W. Lowrie; Attitude determination - James W. Lowrie; Spacecraft performance management and monitoring - James R. Stephens. Philip Carney also provided significant contributions in the areas of on­ board processors and electronics in general. CONTENTS Page I. INTRODUCTION ...... .... .. I-i II.
