Is it a good time to invest in backup technology for potential GPS signal failures?

In October 2026, Infleqtion successfully tested its Tiqker optical atomic clock during a two-week continuous trial aboard the U.S. Navy vessel RV Merlin. The test demonstrated the device's ability to maintain precise timing independent of GPS signals while operating in harsh maritime environments.

Why it matters

This demonstration validates a portable, high-precision timing solution capable of maintaining synchronization in GPS-denied environments. Such technology is essential for naval operations where signal jamming or interference threatens traditional positioning and navigation systems.

The Tiqker optical atomic clock maintained continuous operation for two weeks during the Maritime Big Play Pacific exercise. The test specifically measured the system's resilience to extreme temperature fluctuations and sustained structural vibrations on the RV Merlin.

The players

Infleqtion

A quantum technology company focused on developing cold-atom hardware for timing, sensing, and computing applications.

U.S. Navy

The maritime branch of the United States Armed Forces tasked with evaluating advanced navigation technologies for subsea and surface warfare.

The details

The Tiqker uses laser-cooled atoms to achieve high-accuracy timing, functioning as a standalone reference without relying on external satellite signals. By isolating atomic transitions from environmental noise, the clock remains stable even when subjected to the physical stresses of a naval vessel. This capability allows military hardware to maintain synchronized operations when GNSS (Global Navigation Satellite System) signals are unavailable or compromised.

2024: Infleqtion tested the Tiqker clock on an airborne platform.
2025: The device underwent testing on the UK Royal Navy submarine XV Excalibur.
October 2026: The clock completed a two-week continuous trial aboard the RV Merlin.

The Tech Race

This development marks a shift toward ruggedized, portable atomic clocks that outperform traditional quartz oscillators. It serves as a direct update to the U.S. Navy's PNT modernization initiative aimed at ensuring navigational integrity in contested environments.

While currently focused on naval defense, this technology impacts infrastructure reliant on high-precision timing, such as power grids and telecommunications. Commercial availability for broader industrial use remains unannounced as the company focuses on military integration milestones.

The takeaway

The successful operation of the Tiqker clock confirms that portable optical atomic systems are moving from experimental airborne platforms to sustained, heavy-duty maritime use. Observers should track the upcoming results from the Navy's BARB-26 subsea warfare exercise for further data on integration.
