MicroStrain 3DM-CV7-AR Inertial Sensor

MicroStrain 3DM-CV7-AR Inertial Sensor

The 3DM-CV7-AR Inertial Measurement Unit (IMU) and Vertical Reference Unit (VRU) 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-AR in a league of its own when it comes to price and performance.
