• Land and sea applications include high-precision surveying, gimbal stabilization, unmanned aerial vehicles, autonomous vehicles, tunneling and mining, structural monitoring, subsea navigation, infrastructure monitoring, and hydrography.

The Boreas A series provides accurate and reliable IMU/AHRS solutions with a significant reduction in Size, Weight, Power, and Cost (SWaP-C). It integrates Digital Fibre Optic Gyroscope (DFOG) and closed-loop accelerometer technologies with AI-based fusion algorithms. The unit offers ultra-fast north-seeking capability, making it suitable for GNSS-denied environments.
