Abstract
This paper discusses the design, fabrication, and testing of a single axis reaction wheel testbed with optical object tracking. Reaction wheels enable satellites to control their attitude. This system can autonomously correct its attitude about a single axis and track an external object using an on-board camera. Tests were performed to calibrate the system and drive further iteration in the design. This system is intended for research and educational applications, including exploring satellite attitude control with aspects of hardware and software integration. Future work includes refinement of the object tracking algorithm and state estimation system to provide for more robust control, especially when switching between tracking objects and maintaining constant attitude. In addition, elements of feedforward control could be applied to this system, such as the addition of flywheel angular velocity estimation.
