3 Axis Servo Turntable with High-Speed Antenna Work Positioning System for SATCOM

The SOTM 3-Axis Servo Turntable (Model: ZD-703-SFDZD-XX) is an advanced motion control platform engineered for precision positioning of RF payloads. Its independently controlled azimuth, pitch, and polarization axes achieve omnidirectional steering with 0.01° resolution, enabling critical applications in SATCOM terminals and EW systems. The turntable’s military-grade robustness is demonstrated by an extended operating temperature range (-45°C to +65°C) and IP65 environmental sealing, ensuring reliability in airborne, maritime, and vehicular deployments under harsh conditions.

Architected with a modular servo system, the platform offers dual direct-drive/gear-drive transmission modes, balancing smooth low-speed operation with rapid 100°/s scanning. The zero-position preset function and ultra-fine angular resolution support mission-critical tasks such as phased array beamforming and LEO satellite tracking. Integrated low-loss slip rings and customizable waveguides maintain signal integrity up to Ka-band frequencies, overcoming rotational signal degradation challenges.

Technologically, the closed-loop servo control algorithm dynamically compensates for mechanical distortion and wind loads, achieving ±0.1% velocity stability for moving platforms. Programmable Z-pattern and cross-scanning modes, coupled with flexible RS422/Ethernet protocols, enable seamless C4ISR integration. Key applications include:

• SATCOM: Stabilized antenna pointing for mobile terminals

• Electronic Warfare: Agile beam steering for jamming systems

• Testing: Multi-angle RCS measurement for stealth platforms

With its compact footprint (<15kg) and 48VDC±10% wide-voltage input, this system delivers unprecedented motion control capabilities for SWaP-constrained UAVs and mobile reconnaissance systems.
