MicroStrain 3DM-GV7-AHRS Inertial Sensor

The 3DM-GV7-AHRS is a ruggedized, tactical-grade Attitude and Heading Reference System (AHRS) featuring a fully calibrated MEMS-based accelerometer, gyroscope, and magnetometer, housed in a compact IP68-rated aluminum enclosure. It delivers high-accuracy roll, pitch, and heading data using an onboard Extended Kalman Filter, making it ideal for robotics, UAVs, and other demanding applications.
