摘要

Architecture choices impact planning and scheduling of activity sequences for two widely separated spacecraftenvisioned to be part of an astrophysics mission to observe extra-solar-planets. The two spacecraft consist of a largespace telescope and an external occulter, separated by tens of thousands of kilometres. The science need is to maintainalignment at the tens of milliarcseconds level (~ metres) or less on given target stars after moving one of the spacecrafttens of thousands of kilometres. Doing this efficiently presents operational and architectural design challenges that relyon appropriate choice of navigation, propulsion, and alignment technologies, vehicle configuration, and activityscheduling strategies—an extensive combination of which may potentially be chosen from for such a mission.Challenges inherent in the general system architecture are described with emphasis on potential problems and the needfor sound and appropriate integration of architecture planning, subsystem choice, and activity scheduling.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
