Advanced Navigation has launched two new fibre-optic gyroscope (FOG) navigation solutions, the Boreas A90 and Boreas A70.

The devices are strategic-grade inertial measurement units that deliver acceleration and orientation under all conditions with no reliance on GNSS using the company’s patented Digital FOG technology (which uses a specially developed digital modulation technique that passes spread spectrum signals through a closed-loop optical coil).

They also feature automatic gyrocompassing which, the company claims, has led to a reduction in size, weight, power and cost compared to competing systems on the market.

Advanced Navigation is targeting applications that require ultra-high accuracy orientation and navigation capabilities, such as marine, surveying, subsea, aerospace, robotics and space.
