SG30-SP Technical Specification
SG30-SP
typeSingle-axis fiber optic gyroscope

The SG30-SP is a fully solid-state digital closed-loop low-to-medium precision single-axis fiber optic gyroscope based on the SAGNAC principle. It consists of an SLD light source, fiber optic coupler, photodetector, integrated optical phase modulator, fiber optic sensing loop, circuitry, and structural components.

Designed specifically for servo stabilization platforms, it features small size, high update rate, low latency, low noise, and high bandwidth, making it an ideal choice for medium-to-low precision angular rate sensors. It can be widely used in various types of stabilization platforms.


  • Single 5V Power Supply: Simplified power integration.

  • High Update Rate: Up to 4000 Hz for real-time dynamic response.

  • Superior Full-Temperature Performance: Stable accuracy across extreme temperature ranges.

  • Instant Start-up: Achieves nominal specifications immediately upon power-up; no warm-up required.

  • Robust Environmental Adaptability: Withstands high-impact shocks and severe vibrations.

  • Interference Fringe Recognition: Supports full-dynamic-range cold starts.

  • High Reliability: Engineered for long-term mission-critical stability.

  • Zero Dead Zone: Ensures continuous, seamless measurement at low rates.
