JT-I MU90 Inertial Measurement System
The JT- IMU90 fiber optic inertial measurement unit uses a three-axis fiber optic gyroscope (FOG) to sense the angular motion of the carrier and output a digital signal proportional to the angular velocity of the carrier. The configured quartz accelerometer senses the linear acceleration of the carrier, providing the best cost-effective solution. Compared with other similar gyro technologies, the fiber optic gyroscope has significant advantages in life and stability.
