An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information including roll, pitch, and yaw. An Attitude and Heading Reference System, also called AHRS, acts as a motion sensor. It contains an IMU (3 gyroscopes, 3 accelerometers, and 3 magnetometers) and adds a central processing unit (CPU) that embeds the Extended Kalman Filter. This allows to calculate highly reliable attitude and heading relative to magnetic north, in addition to roll, pitch, and yaw. Thanks to this sensor fusion, the drift from gyroscopes is compensated by vectors such as gravity and the Earth’s magnetic field. The DIGS100 is specifically designed for downhole drilling applications.
