3DM-CV7-AHRS

The 3DM-CV7-AHRS Inertial Measurement Unit (IMU) and Attitude and Heading Reference System (AHRS) offers tactical grade performance in the smallest and lightest OEM package yet. Each sensor is individually calibrated for optimal performance over a wide range of operating conditions.

 

Our Auto-Adaptive Extended Kalman Filter has been designed from the ground up to deliver consistently reliable measurements in even the most challenging environments. Cutting-edge orientation algorithms, advanced internal time management, and a flexible event triggering system put the 3DM-CV7-AHRS in a league of its own when it comes to price and performance.
