BW-IMU900 Small size Three-Axis Fiber Optic Gyroscope Inertial Measurement Unit
Introduction
BW-IMU900 is a small-sized high-precision three-axis fiber optic gyroscope inertial measurement unit developed and produced by Bewis.
It uses a highly reliable MEMS accelerometer and a three-axis fiber optic gyroscope.The original data deviation is estimated by the 6-state Kalman filter with appropriate gain, and the measurement accuracy is ensured by the algorithm. The parameters are compensated by non-linearity and orthogonality.
