Latest Patents

Brian Stewart holds a patent for a "Momentum biased active three-axis satellite attitude control system." This invention provides control of an active three-axis multiple-wheel attitude control system with a bias momentum to achieve stiffness about the pitch axis. This stiffness allows the system to overcome the limitations of a zero momentum system that relies on the sun as its yaw reference during periods of satellite high noon and midnight. The satellite's attitude is maintained through angular momentum exchange developed by three or more reaction wheels positioned on the satellite. The control mechanism is designed to provide net angular momentum in the pitch axis wheels, achieving the necessary momentum bias or stiffness along the pitch axis, while keeping the time average of angular momentum about the roll and yaw axes substantially zero.
