Type 11 Biaxial Gimbal
The Type 11 biaxial gimbal as shown consists of two Type 1 actuators in an orthogonal combination. The Type 1 actuators can be provided with a variety of options. These gimbals can be used for two-axis antenna or solar array drives. A variety of application specific options can be implemented, including slip rings, cable management systems, and hard stops to limit range of motion. Interfaces can be adapted to fit the application both mechanically and electrically. Where the Type 1 actuator is not suitable for both axes, please keep in mind that actuators of different sizes can be mixed in a biaxial configuration (such as a Type 21 Biaxial Gimbal comprised of a Type2 Azimuth actuator configured with a Type 1 Elevation actuator, for instance) if required.
