Description

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

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