Boreas D90 is an ultra-high accuracy INS that provides position, velocity and orientation under the most demanding conditions. It combines cutting-edge closed-loop Digital Fibre Optic Gyroscope (DFOG) and closed-loop accelerometer technologies, with a dual antenna RTK GNSS receiver.

The Boreas D90 delivers strategic-grade bias stability of 0.001 deg/hr. This allows the Boreas D90 to achieve ultra-high roll/pitch accuracy of 0.005 degrees and heading accuracy of 0.006 degrees. Boreas D90 allows for full GPS independence with dead reckoning accuracy of 0.01% distance traveled with an odometer or DVL.

This next-generation FOG features ultra-fast gyro compassing, taking only 2 minutes to acquire heading in both stationary environments or on the move. The gyro compassing allows the system to determine a highly accurate heading of 0.01 degrees secant latitude without any reliance on magnetic heading or GPS.

Boreas D90 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.
