The Royal Navy has trialed Infleqtion’s Tiqker quantum optical atomic clock aboard the testbed submarine XV Excalibur, demonstrating ultra-precise timing for navigation under GPS-denied conditions.

Unlike surface vessels, submarines rarely surface to access GPS signals and instead rely on internal systems such as inertial navigation and acoustic positioning.

Precise timing is essential for navigation systems, as minor sensor errors can gradually accumulate and cause the system’s position estimate to drift.

According to Infleqtion, the clock’s atomic transition frequency is 10,000 times higher than that of microwave clocks, resulting in superior precision and environmental stability.
