CubeSats have evolved to the point where high accuracy inertial pointing has become a requirement in certain missions. In these missions, three reaction wheels are required to provide 3-axis control throughout the entire orbit. Sensors are chosen to provide the level of accuracy required for a specific mission. We have developed a 3-axis system that builds on the experience and hardware heritage gained from the Y-Momentum unit. This system can be upgraded to a variety of levels to provide different pointing abilities for different missions.
