A variable speed control moment gyroscope (VSCMG) having a desired offset between the center of mass of the gimbal frame and the center of mass of the flywheel. This gives the VSCMG a higher control authority than an otherwise identical VSCMG without the desired offset at identical gimbal and flywheel rotation rates. Thus the VSCMG generates more angular momentum and torque than an otherwise identical VSCMG without the desired offset at identical gimbal and flywheel rotation rates and per the same unit power consumption. The VSCMG can be operated without any control singularities in a map between the gimbal rate and/or the flywheel rate and the angular momentum or torque produced by the VSCMG. The desired offset is typically at least an order of magnitude greater than an offset between the center of mass of the gimbal frame and the center of mass of the flywheel occurring during manufacture of the VSCMG due to manufacturing tolerances.
