New range of fibre optic gyroscope inertial navigation systems


The Boreas D90 is an ultra-high accuracy, strategic-grade INS, offering a 40% reduction in size, weight, power and cost relative to competing systems. Boreas D90 is the first product to be released that is based on Advanced Navigation’s new DFOG (Digital Fibre Optic Gyroscope) technology, which is the culmination of 25 years of development involving two research institutions.

The Boreas D90 is targeted at applications requiring always available, ultra-high accuracy orientation and navigation including marine, surveying, subsea, aerospace, robotics and space.

Advanced Navigation’s CEO, Xavier Orr said “Boreas D90 is the first product on the market to offer our patent pending DFOG technology. DFOG represents a step change for fibre optic gyroscopes. With Boreas’ ultra-high accuracy and strategic-grade performance combined with the reduction of size, weight, power and cost by 40%, we will be able to enable new industries and applications that were never possible before.”

The Boreas D90 delivers a strategic-grade bias stability of 0.001 deg/hr. This allows the Boreas D90 to achieve ultra-high roll/pitch accuracy of 0.005 degrees and heading accuracy of 0.006 degrees. Boreas D90 allows for full GPS independence with dead reckoning accuracy of 0.01% distance travelled with an odometer or DVL.

This next generation FOG features ultra-fast gyrocompassing, taking only 2 minutes to acquire heading in both stationary environments or on the move. The gyrocompassing allows the system to determine a highly accurate heading of 0.01 degrees secant latitude without any reliance on magnetic heading or GPS. Boreas D90 contains Advanced Navigation’s revolutionary sensor fusion algorithm. This algorithm is more intelligent than the typical extended Kalman filter and is able to extract significantly more information from the data by making use of human-inspired artificial intelligence. It was designed for control applications, with a high level of health monitoring and instability prevention to ensure stable and reliable data.

Advanced Navigation has designed Boreas D90 from the ground up for reliability and availability. Both the hardware and software are designed and tested to safety standards and it has been environmentally tested to mil standards. The system is designed for a mean time between failure of 500,000 hours. Additional features of the Boreas D90 include Ethernet, CAN and NMEA protocols, as well as a disciplined timing server providing PTP. 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.
