90 laser gyro is a high-precision digital 90-type two-frequency machine-shaking laser gyro produced by our company. It has the advantages of high precision, simple power supply, High level of integration, and digital output. It can measure the angular motion of the carrier around its sensitive axis. , the output is two quadrature square waves. It can be widely used in positioning/navigation, surveillance/reconnaissance, fire control, and flight control in the fields of rockets , missiles and their launch vehicles , aircraft , ships , and armored vehicles .
Functions Measure the rotation angle around its sensitive axis, and output two orthogonal square waves containing rotation information.
Performance The main technical indicators that the gyroscope meets are shown in Table 1.
