Product Description

RLG (Dubhe-90)

The Ring Laser Gyroscope (RLG) operates based on the Sagnac effect, measuring angular increments by detecting the phase difference between counter-propagating laser beams within a closed glass cavity.

With high integration, exceptional reliability, strong environmental adaptability, and stable performance, the Dubhe-90 RLG is widely used in high-precision inertial navigation systems (INS).

Applications

The Dubhe-90 RLG is suitable for navigation and attitude reference in:

Spacecraft
Aircraft
Satellites
Vehicles
Ships
Submersibles

Key Features

Monolithic optical and electronic packaging, enabling easy installation
Compact and lightweight design with controlled power consumption
High reliability with strong resistance to shock and vibration
Wide dynamic response bandwidth with digital output
