Ask a question

Boreas combines cutting-edge closed-loop Digital Fibre Optic Gyroscope (DFOG) and closed-loop accelerometer technologies with a dual antenna RTK GNSS receiver.

These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable navigation. The system features ultra-fast gyro compassing, acquiring and maintaining an accurate heading under all conditions with no reliance on GNSS.

Boreas is compatible with our post-processing kinematic (PPK) software Kinematica.

Boreas | Digital Fibre Optic Gyroscope (DFOG)

Revolutionary DFOG Technology

Boreas takes Fibre Optic Gyroscope (FOG) technology into the next generation with new, patent-pending Digital FOG (DFOG) technology, developed over 25 years with 2 research institutions. This revolutionary DFOG technology combines a specially designed closed-loop optical coil with advanced spread spectrum digital modulation techniques that have never been used in a FOG before. The resulting DFOG offers dramatically improved accuracy, stability, and reliability with significantly reduced size, weight, power, and cost.

Ultra-Fast North Seeking

The superior accuracy of the DFOG technology enables Boreas D90 to rapidly determine its heading, without the need for GNSS or magnetometers. By sensing the Earth's rotation, Advanced Navigation's revolutionary north-seeking algorithm allows Boreas D90 to acquire an accurate heading within minutes of start up. This can be achieved in both static and dynamic conditions, as well as at high latitudes.

Reliability

Boreas D90 has been designed from the ground up for reliability. Both the hardware and software are designed and tested to safety standards. The precision aluminium enclosure is waterproof and dustproof to the IP67 standard. The system is resilient to shock and vibration, allowing it to be used in the most extreme conditions. The hardware is designed and tested to MIL standards. The GNSS contains RAIM, which excludes malfunctioning or tampered satellite signals.

Industry Leading SWaP-C

Based on ground-breaking DFOG technology, Boreas D90 offers a 40% reduction in size, weight, power and cost, when compared to competing systems of similar performance.

Multi Protocol Support

Boreas D90 features multiple interfaces including Ethernet, CAN, RS232, RS422 and GPIOs. Boreas D90 supports all the industry standard protocols including NMEA, CANopen, NTP, PTP, 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 1 year of data logging.
