THE AUTONOMOUS CLOCK
OPTICAL ATOMIC PRECISION IS STILL CONFINED TO CONTROLLED FIELD DEMONSTRATIONS.
After two decades of miniaturizing laboratory technology, only a handful of bespoke field demonstrations exist.
NO REPEATABLE DEPLOYMENT.
NOTHING RESEMBLING TIMING INFRASTRUCTURE.
The gap is enormous.
THE AUTONOMOUS CLOCK
THE INDUSTRY BUILT ENVIRONMENTAL CONTROL AROUND A SINGLE ATOMIC REFERENCE.
A conventional optical clock measures one atomic transition to set its frequency.
Keeping that atomic reference stable requires expensive environmental control and correction around it.
WHEN THE ENVIRONMENT CHANGES, THE ATOMIC REFERENCE SHIFTS.
TIME DRIFTS WITH IT.
THE AUTONOMOUS CLOCK
PTARMIGAN CHANGES THE ATOMIC REFERENCE ITSELF.
Born from five years of research at NIST, Ptarmigan has developed a fundamentally different compact optical-clock architecture.
TWO ATOMIC TRANSITIONS. ONE MEASURED DIFFERENCE.
Ptarmigan compares two atomic transitions in ytterbium, two precise atomic frequencies inside the same atom.
Environmental shifts shared by both transitions can be identified through the difference between them.
Shared shifts move both. Their difference reveals the error.
ACCURACY BY CONSTRUCTION.
Instead of relying on months of unit-by-unit environmental characterization, the clock measures environmental error at the atomic reference.
The Autonomous Clock.
THAT CHANGES HOW OPTICAL CLOCKS DEPLOY.
ON DEMAND
Built without months of bespoke characterization.
ACROSS ENVIRONMENTS
Precision designed to move with the mission. Across land, sea, air and space.
AT NETWORK SCALE
Networked autonomous clocks form mission-system architecture.
TIMING AUTHORITY INSIDE EVERY SYSTEM.
Each Autonomous Clock gives its mission system a precise local timing reference.
Networked clocks can sustain precise timing for sensing and coordination without continuous GPS steering.
FROM CLOCK TO INFRASTRUCTURE.
One clock gives a mission its own time.
Networked optical clocks become mission system architecture.
Repeatable, networked clocks can become a resilient terrestrial timing layer.
Ptarmigan is closing the enormous gap between a controlled field demonstration and network-wide autonomous timing infrastructure.
