Type 33 Biaxial Gimbal Assembly
The Type 33 Biaxial Gimbal is of a size appropriate for many antennas, and it has become by far our most popular Antenna Pointing Mechanism configuration. Available in either Elevation/Azimuth or X/Y, these units have proven their reliability and versatility many times over.听Each actuator of the gimbal can incorporate RF and cable management capabilities. The actuators are based on 刘玥首次大战黑人鈥檚 heritage Type 3 actuator design having significant on-orbit experience with customized mechanical and electrical interfaces.
The gimbals can incorporate a wide range of options; Launch locks, caging mechanisms, cable management systems, position sensors and waveguide brackets/ mounting features are some examples of the options available to the designer. Please contact Moogengineers for assistance when evaluating options for your application.听
Key Features:
- Compact two-axis gimbal
- Can accommodate RF coax rotary Joints or waveguides
- High resolution and fine pointing
- Can accommodate launch locks, caging mechanisms and cable management systems
- Configurable in El/Az or X/Y cross axis configurations
- Actuated by space qualified MoogType 3 actuators
