Abstract
A biax gimballing arrangement permitting both axes of rotation to intersect at a point within a load being gimbaled, thereby permitting the rotational inertia of the load and the gimbal mechanism itself to be minimized. Gimbal rotation about a first axis is achieved by a first drive motor. Rotation in a second axis orthogonal to the first axis is achieved by a steel cable drive assembly having two drive cable ends that are passed through the first rotational axis on their way to respective anchor points within a portion of the gimbal apparatus that is rotated about the first axis. This rotatable portion of the gimbal apparatus includes milled guideways which permit rotation of the gimbal load mount. The central portion of the cable is driven by engagement with a pulley attached to the shaft of a second drive motor.
