Direct-Drive Two-Axis Tracking Rotary Table
The Direct-Drive Two-Axis Tracking Rotary Table is a high-dynamic motion platform configured with orthogonal azimuth and elevation axes. Utilizing gearless direct-drive actuation, it eliminates mechanical backlash to deliver exceptional dynamic response and sub-arcsecond positioning resolution. Integrated with user-defined control and orbit-propagation software, the platform provides automated, high-precision line-of-sight (LOS) pointing, tracking, and telemetry link maintenance for satellites and orbital space targets.
Features
- Self-weight ≤80 kg, load capacity ≥30 kg
- Azimuth rotation range: ±358°, Pitch range: -5° ~ 95°
- Both axes equipped with locking protection function
- Absolute encoder with resolution of 3 arcseconds
- Excellent open-loop tracking accuracy (tracking error < 0.5″ within 10 seconds)
- Maximum tracking speed: Azimuth ≥10°/s
Applications
Suited for aerospace and astronomical observation applications, deployed in satellite tracking and stellar observation equipment.
