MicroStrain 3DM-CX5-AHRS Inertial Sensor

The MicroStrain 3DM-CX5-AHRS is the smallest and lightest high performance AHRS with an Adaptive Kalman Filter available. It features a fully calibrated and temperature compensated triaxial accelerometer, gyroscope, and magnetometer to achieve the optimum combination of measurement qualities under all dynamic conditions. The dual on-board processors run an exclusive Auto-Adaptive Extended Kalman Filter (EKF) for outstanding dynamic attitude estimates, making it ideal for a wide range of applications, including platform stabilization, robotics, and vehicle health and usage monitoring.
