Boreas A50 & D50
The Boreas 50 Series is a compact, rugged inertial navigation system with a north-seeking gyrocompass that maintains reliable navigation in GPS-denied and harsh environments.
Horizontal Position Accuracy (GNSS RTK)
0.01 m
Roll & Pitch Accuracy
0.03 °
Heading Accuracy (Gyrocompass)
0.5 ° seclat
The Boreas 50 series provides compact, north-seeking gyrocompassing** for accurate heading and orientation, even in GNSS-denied environments.
Boreas 50 series variants:
- A50 provides heading and orientation as an AHRS and INS.
- D50-X20P is a dual antenna all-band GNSS receiver.
- D50-MX5 is a dual antenna multi-band GNSS receiver, with Electronic Protection for resilience against jamming and spoofing threats.
*Certifications expected April 2026.
**Gyrocompassing determines accurate heading from the Earth’s rotation, removing the dependence on GNSS satellites.

Features
FOG Technology
The Boreas 50 fiber optic gyroscope (FOG) is a highly accurate and reliable navigation technology. It’s the result of over 25 years of development in partnership with two research institutions. The gyroscope uses a closed-loop optical coil and an advanced spread-spectrum digital modulation technique to improve accuracy, stability, and reliability while reducing size, weight, power, and cost.
Gyrocompass North-Seeking
The Boreas range of fiber optic gyroscopes (FOGs) can determine heading without needing a Global Navigation Satellite System (GNSS) or a magnetometer. By sensing the Earth’s rotation, the system’s north-seeking algorithm can acquire an accurate heading. This is possible in static and dynamic conditions, even at high latitudes.
Reliability
Boreas 50 has been designed from the ground up for rugged reliability. Both the hardware and software are tested and certified to environmental and electromagnetic standards (MIL-STD 461 and MIL-STD 810H). The precision aluminum enclosure is waterproof and dustproof to the IP67 standard. The system is resilient to shock and vibration, allowing it to be used in extreme conditions.
Industry-Leading SWaP-C
The Boreas 50 FOG Series delivers industry-leading performance with a compact and lightweight design. Excelling in terms of Size, Weight, Power, and Cost (SWaP-C).
Multi-Protocol Support
The Boreas 50 features multiple interfaces, including Ethernet, CAN, RS232, 1PPS, RS422, and GPIOs. It supports industry standard protocols, including NMEA 0183, CANopen, 1PPS, and ANPP, as well as a wide variety of proprietary protocols. A rich, responsive embedded web interface provides full access to all of the device’s internal functions and data. Internal storage allows for up to one year of data logging.
