INS inertial system Boreas D70

high-accuracyGNSSfor UAV

Utilizing world-first Digital FOG technology, the Boreas D70 and D90 deliver high-precision GNSS/INS performance with automatic Gyrocompassing, with the D90 offering an ultra-high accuracy INS and a 40% reduction in SWaP-C (Size, Weight, Power, and Cost) compared to standard solutions. Roll & Pitch 0.01 ° Heading (Gyrocompass) 0.1 ° seclat Bias Instability 0.01 °/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. Features 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 the Boreas range to rapidly determine heading, without the need for GNSS or magnetometers.
