The Boreas range delivers accurate orientation and heading in GNSS denied environments, as an Altitude and Heading Reference System (AHRS), with D variants adding reliable position and navigation as an Inertial Navigation System (INS).

The Inertial Measurement Unit (IMU) is driven by Fibre Optic Gyroscopes (FOG) and accelerometers which feed data into a sophisticated fusion algorithm. All units are certified for rugged environmental conditions.

Boreas north-seeking gyrocompassing determine accurate heading in GNSS denied environments using the earth’s rotation. Positional accuracy and navigation is enabled in D variants using a dual antenna RTK GNSS satellite receiver.
