Abstract: Two-axis positioning apparatus utilizes a yoke including a hub mounted on a base for rotation about a first axis, an integral bight member extending radially away from the hub in opposite directions and a pair of upstanding legs distant from the hub extending away from the bight member at spaced apart locations. A load, such as an antenna, extends between and is mounted on the upstanding legs of the yoke member for rotation about a second axis distant from the bight member. A first drive system rotatably positions the yoke about the first axis and a second drive system intermediate the yoke and the load includes a first drive component rotatable about the first axis for rotatably positioning the load about the second axis as a function of the difference in angular movement of the support member about the first axis and the angular movement of the first drive component about the first axis.
