Space test program standard satellite study
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.
