AHRS Module

AHRS - Attitude and Heading Reference System

The AHRS is also sometimes referred to as an Inertial Measurement Unit, or IMU. It provides feedback on the vehicle's orientation. Measurements include magnetic heading, attitude and rates of change. The AHRS also includes a pressure sensor to determine the depth of the vehicle.

The AHRS compass may require a Magnetic Field Calibration. See the Compass Calibration page for more information.
