70 -type laser gyro is our companys high-precision digital 70-type two-frequency machine-shaking laser gyro. It has the advantages of high precision, simple power supply, high degree of integration, and digital output. It can measure the angular motion of the carrier around its sensitive axis, and output It is two orthogonal square waves. It can be widely used in positioning/navigation, surveillance/reconnaissance, fire control and flight control of missiles and their launch vehicles, aircraft, ships, armored vehicles and other fields .
Functions Measure the rotation angle around its sensitive axis, and output two orthogonal square waves.
Reliability MTBF: 10000h
Performance 70 -type laser gyroscope are shown in Table 1.
