BHP trial records sub-0.1% drift with Boreas and Chimera Land
BHP evaluated Boreas and Chimera Land over a 22-kilometre underground route.
Why it matters
The BHP challenge provides a measured GNSS-denied result for the combined Boreas and Chimera Land architecture across a long underground route, rather than a generic mining-navigation claim.
Evidence notes
- The trial took place at Callio Mine in Pyhäjärvi, Finland.
- The hybrid navigation system operated through a GNSS-denied underground environment.
- Measured inertial-navigation drift remained below 0.1 percent over the route.
Company context
Advanced Navigation develops positioning, navigation and autonomy systems for robots, vehicles and maritime platforms operating in GPS-denied or communications-limited environments.
