Fully Digital FOG INS Launched

Boreas, a new fully digital range of Fiber Optic Gyroscope Inertial Navigation System (INS) has been launched by Advanced Navigation. By DA Team / 28 Oct 2021

The Boreas is an ultra-high accuracy, strategic-grade INS, offering a 40% reduction in size, weight, power, and cost relative to competing systems. Boreas 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 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 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 delivers strategic-grade bias stability of 0.001 deg/hr. This allows the Boreas to achieve ultra-high roll/pitch accuracy of 0.005 degrees and heading accuracy of 0.006 degrees. Boreas allows for full GPS independence with dead reckoning accuracy of 0.01% distance traveled 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 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 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 failures of 500,000 hours. Additional features of the Boreas 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.
