RLG(Dubhe-90)
The Ring Laser Gyroscope (RLG) operates on the Sagnac effect principle, measuring angular increments by detecting phase differences of laser beams in a closed glass cavity. Featuring high integration, exceptional reliability, strong environmental adaptability and stable performance, it has become the sensor of choice for high-precision inertial navigation systems worldwide. Applications include spacecraft, aircraft, satellites, vehicles, ships and submersibles for navigation and attitude reference.
Key features: 1) Monolithic optical/electronic packaging for easy installation; 2) Compact, lightweight design with controlled power consumption; 3) High reliability and shock/vibration resistance; 4) Wide dynamic response bandwidth with digital output.
