BW-AH127C is a low-cost attitude reference system developed and produced by BWSensing. It is equipped with accelerometers, gyroscopes, and magnetometers, and provides reliable information such as heading angle, roll angle, pitch angle, angular velocity, and acceleration for motion vehicles through multi-sensor fusion algorithms. It is suitable for navigation, positioning, and dynamic attitude measurement of unmanned vehicles.
The document is a V3.0 user manual for the BW-AH127C series Modbus protocol low-cost Attitude Reference System (ARS) manufactured by Wuxi BWSensing Technology Co., Ltd. The device integrates an accelerometer, gyroscope, and magnetometer to provide reliable heading, roll, pitch, angular velocity, and acceleration data using a six-state Kalman filter algorithm. This manual is written in Chinese.
