The Boreas A series combines cutting-edge Fibre Optic Gyroscope (FOG) technology with closed-loop accelerometers, which are coupled in a sophisticated fusion algorithm to deliver accurate and reliable orientation. The system features ultra-fast gyrocompassing, acquiring and maintaining an accurate heading under all conditions with no reliance on GNSS.
The Boreas A series can also offer full INS capabilities when provided with an external position source, such as an external GNSS receiver.
Features
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 the Boreas range to rapidly determine heading without the need for GNSS or magnetometers. By sensing the Earth’s rotation, Advanced Navigation’s revolutionary north-seeking algorithm allows Boreas 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 has been designed from the ground up for rugged reliability. Both the hardware and software are designed and tested to safety standards. The precision aluminum enclosure is waterproof and dustproof to the IP67 standard. The system is resilient to shock and vibration, allowing them to be used in the most extreme conditions. The hardware is designed and tested to MIL standards. The GNSS variants contains RAIM, which excludes malfunctioning or tampered satellite signals.
Industry-Leading SWaP-C
Based on ground-breaking DFOG technology, the Boreas range offers industry-leading size, weight, power and cost, when compared to competing systems of similar performance.
Multi Protocol Support
The Boreas range features multiple interfaces including Ethernet, CAN, RS232, RS422 and GPIOs. It 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.
