Overview
Ring Laser Gyroscope Two Frequency Machine Shaking 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.
JIO90-RLG is available in A, B and C models to meet your different needs.
Features
Measure the rotation angle around its sensitive axis, and output two orthogonal square waves containing rotation information.
Performance
The main technical indicators that the laser gyroscope meets are shown in Table 1.
