Product Description

BW-IMU720 Small-size three-axis fiber optic gyroscope inertial measurement unit Accelerometer range:±20g




IMU720 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.
