Advanced Navigation successfully demonstrated a breakthrough in underground navigation, delivering high-precision positioning without reliance on fixed infrastructure or GNSS, in Europe’s deepest underground mine in Pyhäjärvi, Finland.
The Hybrid Navigation System, combining a Laser Velocity Sensor with the Boreas D90 fiber-optic gyroscope Inertial Navigation System, achieved consistent sub-0.1 percent navigation error across multiple runs, without relying on any fixed positioning infrastructure, pre-existing maps or external aiding.
