Catalog excerpts

The Boreas A series offers accurate and reliable IMU/AHRS solutions with an industry-leading reduction in SWaP-C. Boreas combines groundbreaking Digital Fibre Optic Gyroscope (DFOG) and closed-loop accelerometer technologies with the latest AI-based fusion algorithms. With ultra-fast north-seeking capability, the unit offers accurate heading without reliance on magnetometers or GNSS. This makes Boreas the ideal choice for demanding GNSS-denied scenarios where a cost-effective, high performance, solution is required. The Boreas A Series can optionally be upgraded to full INS functionality and combined with an external GNSS input.
