Ultra-Performance Type 3 Actuator and Gimbal
The Ultra Performance Type 3 (UPT3) Actuator and UPT3G Biaxial Gimbal are designed to implement features, improvements and technology enhancements accumulated from over 40 years of experience in producing pointing and actuating mechanisms for the space industry. The UPT3 Actuator is a closely integrated package that utilizes all available space to significantly increase performance and reliability. While design and performance margins are elevated with the introduction of this actuator, key interface envelope dimensions of the Moog heritage Type 3 are preserved to facilitate interchangeability.
Key Features:
- Closely integrated modular design
- Through-hole egress provides passage for cables and RF rotary joints
- Moog QuieSense position telemetry device provides noise free operation
- Very fine output resolution provides fine pointing
- High torsional and moment stiffness
- Fully adjustable external hard stops
