High Stability Single Axis Fiber Optic Gyro with RS422 Output for Navigation System
Product Description
F50 single-axis fiber optic gyroscope is an all-solid-state medium-precision angular rate inertial sensor device that integrates light, machinery and electricity. The product has the characteristics of high precision, small size, light weight, high reliability and high cost performance.
The zero bias stability of the product is less than or equal to 0.5°/h (10s smooth), the response frequency bandwidth, +5V DC power supply, power less than 4W, and the RS422 digital communication method is adopted, which is convenient for users to use, and is an ideal inertial device to replace the traditional mechanical gyroscope.
Application areas: applications in medium-precision inertial navigation systems, positioning and orientation systems, attitude measurement systems, servo stabilization systems, etc.
Composition
a) optical path unit: including erbium-doped light source, fiber ring, integrated optical phase modulator, fiber coupler, photodetector;
b) circuit unit: light source driving circuit, detection and control signal circuit board;
c) Gyro structural parts.
