Ring Laser Gyroscope-JIO70

JIO70-RLG laser gyroscope is a high-precision digital dual-frequency machine shaking laser gyro produced by our 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 wave around the sensitive axis and output two quadrature square waves. It can be widely used in the integration of positioning/navigation, surveillance/reconnaissance, fire control and flight control of missiles and their carrier rockets, aircraft, unmanned aerial vehicles, ships, ships, armored vehicles and other fields.
