Feature
Application
BW-IMU720 is a small-size high-precision three-axis fiber optic gyroscope inertial
measurement unit developed and produced by Bewis Sensing. It 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.
BW-IMU720 has a built-in three-axis fiber optic gyroscope and a highly reliable MEMS
accelerometer. The original data deviation is estimated by the 6-state Kalman filter with
appropriate gain, and the measurement accuracy is guaranteed by the algorithm, and the
nonlinear compensation, quadrature compensation, Temperature compensation and drift
compensation, etc., are used to greatly eliminate errors and improve product accuracy. This
product has a digital interface, which can be easily integrated into the system.
