Advanced Navigation launches Boreas digital FOG
Advanced Navigation has launched a new fiber-optic gyroscope inertial navigation system (INS), named Boreas. It is an ultra-high accuracy, strategic-grade INS, offering a reduction in size, weight, power and cost. Boreas is the first product to be released based on Advanced Navigation’s new DFOG (digital fiber-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.
“Boreas is the first product on the market to offer our patent-pending DFOG technology,” said Advanced Navigation CEO Xavier Orr. “DFOG represents a step-change for fiber-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 it to achieve ultra-high roll/pitch accuracy of 0.005 degrees and heading accuracy of 0.006 degrees. Boreas allows for full independence from GPS with dead-reckoning accuracy of 0.01% distance traveled with an odometer or Doppler velocity log.
The Boreas features ultra-fast gyro compassing, taking only 2 minutes to acquire heading in both stationary environments or on the move. Gyro compassing allows the system to determine a highly accurate heading of 0.01 degrees secant latitude without relying on magnetic heading or GPS.
The Boreas contains Advanced Navigation’s sensor-fusion algorithm, which is more intelligent than the typical extended Kalman filter. The algorithm 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 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 include Ethernet, CAN and NMEA protocols, as well as a disciplined timing server providing PTP. An embedded web interface provides full access to all of the device’s internal functions and data. Internal storage allows for up to one year of data logging.
