Product Description

BW-AH425C High precision CAN Attitude Heading Reference System Pitch±90º,Roll±180º Pitch/Roll accuracy 0.2°



BW-AH425C provides reliable heading and roll angle for motion carriers through multi-sensor fusion algorithms, pitch angle, angular velocity, acceleration and other information. The attitude data deviation is estimated by 6-state Kalman filter with appropriate gain, which is suitable for navigation, positioning and dynamic attitude measurement of unmanned vehicles.
