Case Study: Constraining Drift & Exceeding Sub ~0.1% Accuracy in BHP’s Deep Underground Mining Challenge

Discover how Advanced Navigation exceeded sub ~0.1% error rate over distance traveled (6km) without prior knowledge of the mine layout or using any existing infrastructure.

Reliable navigation and positioning in underground mining environments remains a significant challenge due to the absence of GNSS.

Conducted within Europe’s deepest base metal mine, this case study reveals a breakthrough in underground mining navigation. Combining the Boreas D90 Fibre-Optic Gyroscope-based Inertial Navigation System (INS) and the Chimera Land Laser Velocity Sensor (LVS), Advanced Navigation demonstrated a hybrid navigation system tailored for underground mining that thrives in the harshest GNSS-interrupted environments.
