Abstract
High-accuracy pointing capabilities are desired for many three-axis stabilized small satellites. Momentum-based attitude control system actuators, initially developed for larger satellites, are being utilized by small satellites to meet these pointing requirements. This paper provides an overview of momentum devices available for small satellite applications and three-axis attitude control system (ACS) configurations using these devices. Factors affecting the selection and sizing of ACS components are also addressed. Included are suggestions for potential ACS improvements and cost-saving measures that will make momentum devices more accessible to the small satellite community.
