Product Description

RLG (Dubhe-90) – High-Precision Ring Laser Gyroscope for INS

The Dubhe-90 Ring Laser Gyroscope (RLG) is a high-precision inertial measurement sensor based on the Sagnac effect, engineered for advanced inertial navigation systems (INS). By detecting the phase difference between counter-propagating laser beams inside a monolithic glass cavity, the Dubhe-90 provides high-accuracy angular rate and attitude measurements with ultra-low drift.

Designed for aerospace and demanding mission environments, the Dubhe-90 features long-term bias stability, low noise, wide dynamic bandwidth, and high environmental robustness, making it suitable for both civilian and defense-grade navigation applications.

Applications

The Dubhe-90 Ring Laser Gyroscope is widely used in:

  • Spacecraft and launch vehicles

  • Aircraft and UAV inertial navigation systems

  • Satellites and space platforms

  • Land vehicles and autonomous systems

  • Marine vessels and submarines

  • High-precision attitude and heading reference systems (AHRS)

Key Features

  • Monolithic optical and electronic integration, enabling easy installation and high system reliability

  • Compact and lightweight design with optimized and controlled power consumption

  • High reliability with strong resistance to shock and vibration, suitable for harsh environments

  • Wide dynamic response bandwidth with high-resolution digital output, supporting real-time navigation and control

The Dubhe-90 RLG provides ultra-low bias drift, stable performance, and long operational life, making it an ideal core sensor for advanced INS, navigation, and attitude reference systems.
