Abstract:
This study concerned the conceptual design of a modular spacecraft for performing a large class of STP flights. Design approach and performance capabilities were balanced to yield a low-cost system for capturing many missions. The study included a review of weight, power, orientation, orbit, data, and contamination requirements and emphasized equipment groupings which minimize changes without constraining flexibility. The resulting design includes a a core module which contains basic power and communication and data handling functions and provides the shuttle interface with the shuttle, b several options for an orientation module containing attitude reference and control equipment, c a solid rocket or hydrazine propulsion module for accomplishing transfer from the shuttle orbit to the desired one, d a payload cluster for collecting payloads and interfacing them with the remaining modules, and e standard solar array panels and structures.
