Two-Axis Tracking Rotary Table
The Two-Axis Tracking Rotary Table is a high-precision motion platform configured with orthogonal azimuth and elevation axes. Engineered for target acquisition, trajectory tracking, and line-of-sight (LOS) stabilization, it serves as an ideal baseline carriage platform for electro-optical/infrared (EO/IR) payloads, SATCOM antennas, and radar tracking assemblies. Powered by high-dynamic servo drives and guided by absolute encoder feedback, it delivers exceptional angular positioning accuracy and smooth velocity control across dynamic operating environments.
Features
- Dual-axis table-type precision structure
- Load capacity: 80 kg
- Rotational accuracy: ±3″s
- Angular position positioning accuracy: ±3″
- Excellent rate stability over a wide range
- Arcsecond-level open-loop tracking performance
Applications
Suited for electro-optical tracking and astronomical observation applications. Integrated with telescopes, optical systems or satellite antennas, it enables precise tracking of stellar and space targets.
