FeaturedFrameless Fiber Coil
High-performance fiber coil winding optimized for low bias drift, tight tolerances, and long-term stability.
Precision in every turn.
FOG coils, built on-shore.
Precision fiber coils and optomechanical assemblies for autonomous mobility, aerospace, and robotics. Built in California, for programs where performance and supply can’t slip.
FeaturedAbout & Technology

Drag to rotate
An interactive 3-axis fiber-optic gyroscope. Counter-propagating beams through three orthogonal coils use the Sagnac effect to measure rotation in all axes, no GPS required.
Built upon 15+ years of production-ready processes, paired with founder FOG expertise, and manufactured in California.
Production-ready capability
Proven processes, custom winding equipment, and proprietary test methods deliver production-grade output from our California facility.
Custom Winding Systems
In-house systems engineered for high-performance coil geometries and winding patterns.
Proprietary Potting
Thermally conductive adhesives that hold performance through vibration and temperature extremes.
Multi-Pattern Precision Coil Winding
Proven octupole, quadrupole, and modified quadrupole patterns.
Comprehensive Testing
Proprietary in-process testing at every stage, ensuring every coil meets stringent optical and mechanical specs.
Our Approach
Coil winding is where FOGs are won or lost.
A handful of failure modes separate a tier-1 coil from a mediocre one. We engineer our process around every one of them.
One discipline, both extremes. Ultra-long navigation coils and ultra-compact UAV coils pull in opposite directions, yet both demand the same rigorous process control to preserve Shupe stability, PER, and insertion loss.
Competitive landscape
The coil is the heart
of every FOG.
End-to-end capability from fiber to full optomechanical assembly, with the test coverage and non-competing posture integrators need.
Markets & Applications
Where the demand concentrates.
The common thread: precise position and heading where GPS can’t reach — underground, underwater, indoors, or moving too fast for a fix.
Team & Contact
Decades of photonics and
inertial-sensing experience.
