Optical Gyroscope INS for Underground Mining

Vehicle-mounted optical gyroscope inertial navigation system (INS) for autonomous and semi-autonomous underground mining operations. Reliable positioning, orientation, and navigation in GNSS-denied and extreme environments.

Why Underground Mining Needs INS

In underground mining environments:

• Satellite signals are unavailable

• Traditional navigation fails

• High vibration, dust, moisture, and temperature challenges exist

Our optical gyroscope INS provides a fully autonomous navigation solution for mining trucks, drilling rigs, roadheaders, and underground loaders. It ensures real-time position, velocity, and attitude data for safer and more efficient mining operations.

Core Technology

• Laser / Fiber Optic Gyroscopes

• Quartz Accelerometers

• Strapdown INS Architecture

The system operates independently of external signals and is designed to deliver centimeter-level accuracy, high update rates, and continuous real-time navigation.

Flexible Navigation Modes

• Pure Inertial Navigation — fully signal-denied tunnels

• INS + GNSS Integration — surface & transition areas

• INS + Odometer Integration — underground vehicles

• Zero-Velocity Update (ZUPT) — drift suppression for long-term accuracy

Designed for Extreme Mining Environments

• High-temperature resistance

• Strong vibration & shock tolerance

•  Dust- and moisture-resistant

•  Minimal recalibration, reduced downtime

The strapdown INS design rigidly fixes sensors to the vehicle, enabling precise measurement of acceleration and angular velocity, supporting precision mining and continuous operation.

Mining Applications

• Autonomous mining trucks

• Drilling rigs & roadheaders

• Underground loaders & transport systems

Benefits for Mining Operators

• Centimeter-level positioning accuracy

• Industrial-grade reliability

• Real-time navigation for improved safety

• Enhanced operational efficiency and productivity
