NorthPoint™ Gyro (AHRS) Attitude Heading Reference System — SQ-NPG

The SQ-NPG NorthPoint™ Gyro is an Attitude Heading Reference System (AHRS) that provides true clean angle even in the presence of high shock, acceleration, vibration and transient magnetic disturbance.  It also provides a north reference for Yaw enabling reliable pointing and return-to-home applications.

The system employs high stability, temperature compensated ceramic packaged MEMS accelerometers, gyroscopes, and magnetometers for excellent long term performance and reliability.

The complexity of multi-axis inertial calibrations, quaternion angles, Kalman filters, and dynamic adaptive sensor fusion is handled by the sensor itself.  The SQ-NPG is the ultimate drop-in upgrade for legacy, static inclinometers and magnetic AHRS systems.
