Abstract:
An optical tracking device, includes an azimuth sub-assembly providing a 360-degree range of motion and a transducer sensing the azimuth position within this range of motion; and an elevation sub-assembly coupled to the azimuth sub-assembly and providing at least a −30-degree to +100-degree range of motion and a transducer sensing the elevation position. A cross-elevation sub-assembly is coupled to the elevation sub-assembly and provides at least a ±14-degree optical range of motion and a transducer sensing the cross-elevation position. An elevation gyroscope is affixed to the elevation sub-assembly and generates an elevation rate signal; and a cross-elevation gyroscope is affixed to the elevation sub-assembly and generates a cross-elevation rate signal. A controller receives the azimuth, elevation, and cross-elevation position signals, and the elevation and cross-elevation rate signals and sends command signals to the sub-assemblies to initiate movement to allow inertially stabilized tracking of an object.
