Operating in GNSS-degraded environments often forces a frustrating choice.
Mining and operations managers face the fundamental trade-off of either relying on slow, costly manual processes for precision tasks, or deploying unreliable perception-based systems prone to localization errors.
Advanced Navigation’s Chimera Land Laser Velocity Sensor (LVS) overcomes this compromise.
As a Velocity Aiding System to be paired with an Inertial Navigation System (INS), Chimera Land provides the unambiguous localization and 3D velocity data required to maximize output, ensure safety compliance, and prepare your mine for the future of underground autonomy.
“We’ve worked in underground environments for decades. Seeing this level of precision achieved on the first run signals huge potential for safer and more efficient underground vehicle operations.”
Olli Mylläri, Vice President Technology at Normet

Chimera Land Features
Highly Accurate 3D Velocity
Measures a vehicle’s 3D body velocity with extraordinary accuracy and update rate, enabling tracking of complex movements, such as vibration, wind buffering, or wheel slip. Chimera Land achieves this measurement sensitivity by employing advanced infrared (IR) laser Doppler velocimetry which operates at much shorter wavelengths than conventional radar.
Exceptional Long-Duration Dead-Reckoning
When the LVS is combined with one of Advanced Navigation’s high performance INS, the INS’ performance is significantly enhanced, delivering exceptional long-duration dead-reckoning accuracy. This is especially valuable underground, or in GNSS denied, jammed and spoofed environments.
Effective Across Diverse Terrains
Chimera Land is designed for high-performance operation across diverse terrains. It handles natural surfaces such as sand, dirt, rock, grass, and gravel, alongside paved infrastructure such as bitumen and concrete roads. Its capability extends to complex environments including mountains, tunnels, and open pits.
Rugged Reliability
The LVS is certified to withstand the dust, vibration, and extreme temperature variations found in underground mining environments.
