Product Description

BW-IMU700 Small-size three-axis fiber optic gyroscope inertial measurement unit Gyro bias stability:≤0.1°/h




The BW-IMU700 can output acceleration and angular velocity information without relying on external signal input, which can be calculated through user-developed algorithms The azimuth angle, roll angle, pitch angle, Euler angle, and quaternion information of the measured carrier are suitable for inertial attitude measurement under various states of motion, vibration or static.
