JT-I MU 1 35 Inertial Measurement System
The JT-IMU135 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; three orthogonally configured quartz flexible accelerometers sense the linear acceleration of the carrier, providing the best cost-effective solution. Compared with other similar gyro technologies, fiber optic gyroscopes have significant advantages in life and stability.
