Ring Laser Gyroscope High Precision Two Frequency Machine Shaking

Ring Laser Gyroscope High Precision Two Frequency Machine Shaking is a high-precision digital dual-frequency machine-shaking laser gyro developed and produced by JIoptics company. It has the advantages of high precision, simple power supply, high integration and digital output. It can measure the angular motion of the carrier around the sensitive axis and output two orthogonal square waves. It is widely used in the integration of positioning/navigation, fire control and flight control, surveillance and reconnaissance systems in the fields of missiles and their launch vehicles, ships, aircraft, drones, and armored vehicles.
