Product Description

BW-AH327 Series Low-Cost CAN Bus Attitude And Heading Reference Angle random walk coefficient <0.1 °/√h




BW-AH327 has a built-in high-precision accelerometer, gyroscope and magnetometer, and it provides reliable heading and roll angles for the moving carrier through a multi-sensor fusion algorithm, Pitch angle, angular velocity, acceleration and other information.At the same time, the sealing design and strict production process ensure that the product can still work reliably in harsh environments.
