Using world-first Digital FOG technology, Boreas D90 is an ultra-high accuracy INS offering 40% lower SWaP-C. Roll & Pitch 0.005 ° Heading (Gyrocompass) 0.01 ° seclat Bias Instability 0.001 °/hr Position Accuracy 10 mm Boreas combines cutting-edge closed-loop Digital Fibre Optic Gyroscope (DFOG) and closed-loop accelerometer technologies with a dual antenna RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable navigation. The system features ultra-fast gyro compassing, acquiring and maintaining an accurate heading under all conditions with no reliance on GNSS. Boreas is compatible with our post-processing kinematic (PPK) software Kinematica. Revolutionary DFOG Technology Boreas takes Fibre Optic Gyroscope (FOG) technology into the next generation with new, patent-pending Digital FOG (DFOG) technology, developed over 25 years with 2 research institutions. This revolutionary DFOG technology combines a specially designed closed-loop optical coil with advanced spread spectrum digital modulation techniques that have never been used in a FOG before. The resulting DFOG offers dramatically improved accuracy, stability, and reliability with significantly reduced size, weight, power, and cost. Ultra-Fast North Seeking The superior accuracy of the DFOG technology enables Boreas D90 to rapidly determine its heading, without the need for GNSS or magnetometers. By sensing the Earth's rotation, Advanced Navigation's revolutionary north-seeking algorithm allows Boreas D90 to acquire an accurate heading within minutes of start up. This can be achieved in both static and dynamic conditions, as well as at high latitudes.
