Technical Session VIII: Attitude Control Technologies
Abstract
This paper describes the Attitude Control Subsystem (ACS) for the Spartan Lite spacecraft bus. The performance requirements, the subsystem configuration, the components, the attitude determination algorithm, and the control law (modified from the Small Explorer spacecraft control law) are presented. Subsystem performance is predicted using the TreetopsTM Dynamic Simulator. The ideal performance (obtainable with an ideal attitude sensor) is identified to potential users of the spacecraft bus as an indicator of performance approachable with additional user-provided fine sensors.
