Type 120 Fiber Optic Gyroscope.Fiber optic gyro

The 120-type fiber optic gyroscope is a compact, high-precision closed-loop fiber optic gyroscope. It offers advantages such as fast start-up time, stable performance over a wide temperature range, small size, and light weight. It is designed to meet the requirements of medium- to high-precision inertial navigation systems, including land-based positioning and orientation, vehicle-based heading finding, airborne attitude control, and marine gyrocompass.

Solution

Positioning and Orientation: The 120-type fiber optic gyroscope offers exceptional stability and repeatability, providing extremely accurate angular rate measurements. It can be integrated into land-based positioning and orientation systems, accurately determining the position and direction of vehicles, robots, and other platforms with high precision.

Vehicle-based Heading Finding: With its high precision and fast start-up time, the 120-type gyroscope is suitable for vehicle-based heading finding applications. By measuring the angular rate of the vehicle's movement, it provides accurate heading information, enabling precise navigation and direction finding.

Airborne Attitude Control: The compact design and excellent performance of the 120-type fiber optic gyroscope make it ideal for airborne systems requiring high-precision attitude control. It provides reliable measurements of attitude changes, ensuring stable flight control and precise maneuvering of aircraft and helicopters.

Marine Gyrocompass: The 120-type gyroscope's high precision and robustness make it suitable for marine gyrocompass systems. By measuring the vessel's angular velocity, it provides accurate heading information, enabling precise navigation and ship steering
