ABSTRACT:
A sighting apparatus is provided for aiming an optical device mounted on a moving platform and having both coarse and fine adjustment. The sighting apparatus includes a fixed base and an outer support ring that is capable of rotation by a drive motor about an azimuthal axis perpendicular to an axis defined by the outer support ring. A support hub is rotatably supported within the outer support ring and is capable of rotation by a drive motor about an elevational axis substantially coincident with the axis defined by the outer support ring. At least one mounting plate is supported by the support hub and the mounting plate is capable of movement about the azimuthal and elevational axes relative to the support hub, and the mounting plate is capable of movement about a roll axis perpendicular to the azimuthal and the elevational axes. The mounting plate is driven about the azimuthal and the elevational axes relative to the support hub by a two axis electromagnetic actuator attached to the mounting plate and the support hub.
