LUC-ANCHOR™ Optical Gyroscope

Navigate Without GPS, Navigate Without Drift

LUC-ANCHOR™ is a revolutionary optical gyroscope using silicon photonics to achieve zero-drift navigation in GPS-denied environments. By putting 50 meters of optical waveguide on a 10mm chip, we deliver fiber-optic performance at MEMS cost—enabling hours of precise navigation underground, indoors, or anywhere GPS can’t reach.

The Underground Problem

70% of industrial robotics operates indoors. 100% of mining happens underground. Yet MEMS gyroscopes drift so badly they lose position in minutes. LUC-ANCHOR™ maintains centimeter-level accuracy for hours without any external reference—because light doesn’t drift.

Killer Applications

Underground Mining - Navigate in Total Darkness

Mining robots operate kilometers underground with no GPS, no landmarks, no external references. One wrong turn means millions in lost equipment.

Success Metrics:

• 8-hour shifts without position drift
• 10cm accuracy over 10km traveled
• Zero recalibration required ever
• 1000g shock survival capability

ROI Impact:

• Survey teams: Eliminate $200K/year cost
• Lost equipment: Prevent $500K/year losses
• Productivity: 20% increase from continuous operation
• Safety: Always know exact location for evacuation

Surgical Robotics - Precision for Hours

During 6-hour brain surgeries, sub-millimeter precision is life-critical. MEMS gyros require recalibration every 30 minutes—unacceptable during surgery.

• Challenge: Maintain 0.1mm accuracy for entire procedure
• Solution: Zero-drift optical sensing
• Result: <0.5mm drift over 6 hours
• Impact: Enable new minimally invasive procedures
