GPS-denied navigation support for underground and industrial mobility.

PhoQtek Labs develops visual, inertial, and sensor-fusion technologies for platforms operating where GNSS/GPS is unavailable, obstructed, or unreliable — tunnels, mines, pipe-jacking, industrial inspection, and underground corridors.

FOG-based inertial sensing is relevant where heading support is needed without satellite visibility. Visual navigation may support localization in visually structured environments, subject to lighting, dust, and sensor placement.

Realistic application areas

• Tunnel navigation
• Mine mobility
• Pipe-jacking guidance
• Trenchless construction support
• Indoor industrial inspection
• Infrastructure mapping
• Robotic inspection
• Automated machinery in GNSS-obstructed sites
• Underground utility and corridor navigation
