The High Cost-effective AHRS (DTBW-AH200C) integrates a 3-axis accelerometer, gyroscope, and magnetometer to provide stable heading, roll, pitch, angular velocity, and acceleration through a multi-sensor fusion algorithm. A 6-state Kalman filter, temperature compensation, and zero-drift correction ensure reliable accuracy even in harsh environments. With a sealed design and easy-to-use digital interface, it is well-suited for navigation and dynamic attitude measurement in unmanned vehicles, drones, robots, assisted driving systems, and underwater equipment.
