Type 22
Antenna Pointing Assembly
The Type 22 Biaxial antenna positioner assembly is a compact two-axis gimbal which is ideally suited for supporting and positioning small to medium sized spacecraft communications antennas. It is based on the Moog Type 2 rotary incremental actuator. The gimbal can be configured with either azimuth-elevation or X-Y (crossed axis) geometry, and several approaches to electrical and RF cable management are available.
Key Features:
- Compact two-axis gimbal
- Can accommodate RF Rotary Joints
- High resolution and fine pointing
- Configurable in El/Az or X/Y cross axis configurations
- Actuated by space qualified Moog Type 2 actuators
