The FSM-9 is a high performance fully calibrated 9-axis inertial measurement unit (IMU) / attitude heading reference system (AHRS). It includes a tri-axial accelerometer, a tri-axial gyroscope, a tri-axial magnetometer and a 32-bit MCU in a rugged enclosure. By fusing the output of these sensors with the onboard  MotionEngine™ software, the FSM-9 provides precise real-time 3D orientation, heading, calibrated acceleration and calibrated angular velocity, as well as more advanced outputs such as cursor. The 9-axis motion output is unmatched in performance at any price point and is ideal for use in HMDs, Virtual Reality systems, and a variety of other applications.




With a rugged housing and USB-ready support, the FSM-9 is a simple way to add 9-axis motion data to your prototype in a broad range of applications
