Advanced Navigation Launches World’s First Fully Digital FOG INS

The Boreas D90 fully digital fibre optic gyroscope inertial navigation system (FOG INS) from Advanced Navigation delivers a bias stability of 0.001 deg/hr, ultra-high roll/pitch accuracy of 0.005 degrees, and heading accuracy of 0.006 degrees By Phoebe Grinter / 18 Jun 2021

Advanced Navigation has announced its new range of fully digital fibre optic gyroscope (FOG) inertial navigation systems (INS). Based on Advanced Navigation’s new digital FOG technology, the Boreas D90 is an ultra-high accuracy, strategic-grade INS, offering a 40% reduction in size, weight, power and cost relative to other similar systems.  

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

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

The system features ultra-fast gyrocompassing, taking only 2 minutes to acquire heading in both stationary environments or on the move, which 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 which 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 for reliability and availability, with both the hardware and software designed and tested to safety standards with environmental testing 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.  

Advanced Navigation CEO, Xavier Orr, said “Boreas D90 is the first product on the market to offer our patent pending digital FOG technology. Digital FOG 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.”
