The GY-955 AHRS module integrates a high-performance 9-axis sensor with onboard Kalman filtering, delivering accurate attitude and heading reference for demanding navigation, control, and positioning applications. Built around the Bosch BNO85 intelligent IMU, this board combines 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer with built-in sensor fusion, providing stable orientation data with minimal external processing. The embedded Kalman filter algorithm fuses multi‑axis sensor data in real time, effectively reducing noise, drift, and jitter to improve the accuracy of angle, attitude, and heading outputs even in dynamic environments.
