Advanced Navigation’s Boreas Digital Fibre-Optic Gyroscope


Advanced Navigation has announced the expansion of its Boreas digital fibre-optic gyroscope (DFOG) range, with the new A Series

 The Boreas A90 and A70 are strategic-grade inertial measurement units (IMU) that deliver acceleration and orientation with superior accuracy, stability and reliability under all conditions with no reliance on GNSS. They also feature automatic gyrocompassing with industry-leading reductions in size, weight, power and cost (SWaP-C) compared to competing systems on the market.

Our world-first Boreas DFOG technology represented a step-change for fibre-optic gyroscopes. The addition of the A Series ensures we have greater ability to meet the rapidly growing demand for ultra-high accuracy solutions, even in the most demanding conditions.

The A Series is an embodiment of industry-leading performance and cost-effectiveness. We look forward to seeing this technology unlock new possibilities across an expanse of fields, from autonomous vehicles and land surveying to subsea navigation and mining,” said Xavier Orr, CEO and co-founder of Advanced Navigation. 

Small Form Factor. Unrivalled Performance

The Boreas A90 and A70 are IMUs that contain ultra-high accuracy DFOG and high performance closed-loop accelerometers. Boreas A90 offers ultra-high performance, while the A70 offers high performance. Featuring ultra-fast gyrocompassing, both systems can acquire and maintain an accurate heading under all conditions with no reliance on GNSS, making them well-suited for surveying, mapping and navigation across subsea, marine, land and air applications.

The Boreas A90 and A70 also offer an optional licence to add INS capabilities and enable integration with external GNSS receivers using Advanced Navigation’s comprehensive range of interfaces and communication protocols.

Boreas A90

  • 0.005° roll and pitch
  • 0.01° seclat latitude heading (gyrocompass)
  • 0.001° /hour bias instability
  • 1000 Hz update rate

Boreas A70

  • 0.01° roll and pitch
  • 0.1° seclat latitude heading (gyrocompass)
  • 0.01° /hour bias instability
  • 1000 Hz update rate

Boreas – The World’s Only Fully Digital FOG

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

The Boreas range 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 the Boreas range from the ground up for reliability and availability. Both the hardware and software are designed and tested to safety standards and have been environmentally tested to MIL standards.
