Product Description

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

The Dubhe-90 Ring Laser Gyroscope (RLG) is a high-performance inertial sensor based on the Sagnac effect, designed for high-precision inertial navigation systems (INS). It measures angular increments by detecting the phase difference between counter-propagating laser beams within a closed monolithic glass cavity, delivering accurate and stable angular rate information.

With high integration, excellent long-term stability, and strong environmental adaptability, the Dubhe-90 RLG has become a preferred solution for space-grade and high-end navigation applications worldwide.

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.
