Boreas D90
The World's First Fully Digital FOG
Boreas takes FOG technology to the next level with new patent-pending digital FOG (DFOG) technology. The revolutionary DFOG technology combines a specially designed closed-loop optical coil with advanced digital signal techniques that have been developed over the last 25 years. The result is a groundbreaking Inertial Navigation System (INS) that provides ultra-high accuracy navigation with the lowest size, weight, power, and cost on the market.

Description
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.
The Boreas D90 delivers 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 gyro compassing, taking only 2 minutes to acquire heading in both stationary environments or on the move. The gyro compassing 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.
