Satellite Tracking Rotary Table
The Satellite Tracking Rotary Table is a high-precision two-axis motion platform configured with orthogonal azimuth and elevation axes. Integrated with satellite communication antennas or high-aperture optical payloads, it is engineered to compensate for the Earth’s diurnal rotation, enabling rapid target acquisition, deterministic pointing, and ultra-precise open-loop tracking of celestial bodies, Low/Medium Earth Orbit (LEO/MEO) satellites, and orbital space targets.
Features
- Two-axis (azimuth / pitch) motion
- Load capacity: 150 kg
- Angular position accuracy: ±3″
- Superior tracking stability
- Stellar tracking error < 1″/h
- Encoder resolution: 1″
Applications
Suited for astronomical observation and satellite communications. Paired with satellite antennas or optical systems, it performs acquisition, pointing and tracking of space targets.
