3DM-CV7-AHRS Attitude & Heading Reference System
The 3DM-CV7-AHRS is an embeddable tactical-grade AHRS in a compact and lightweight OEM form factor, delivering IMU outputs such as acceleration and angular rate as well as computed outputs including highly accurate attitude and heading estimates. The sensor utilizes advanced auto-adaptive Kalman Filter algorithms for superior performance even under highly dynamic conditions, and allows IMU and filtered outputs to be configured independently.
All units are individually calibrated and fully temperature-compensated for optimal performance, and feature continuous built-in test capabilities. The rugged machined aluminum enclosure provides protection in demanding environments with high levels of shock and vibration.
