Ring Laser Gyro-70

SKU: RLG-TL70

Overview

70 -type laser gyro is our company’s 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

Continuous working time: the continuous working time is not less than 24 hours after power-on.
