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