RLG (Dubhe-90)
The Dubhe-90 Ring Laser Gyroscope (RLG) operates based on the Sagnac effect, measuring angular increments by detecting phase differences between counter-propagating laser beams in a closed glass cavity.
With high integration, excellent reliability, strong environmental adaptability, and stable performance, the Dubhe-90 has become a widely used sensor for high-precision inertial navigation systems (INS).
