Resilient timing for a GNSS-dependent world

In today’s connected society, critical infrastructure depends on precise time synchronization. Utility networks, government systems, communications, logistics, and financial networks all rely on accurate timing to keep data moving safely and securely. Traditional network synchronization often depends on GNSS signals, which creates vulnerability. If GNSS signals are disrupted, timing systems can lose accuracy, putting critical operations at risk.

The challenge

GNSS-based timing is efficient, but it is not always resilient. Jamming, spoofing, or signal loss can interrupt synchronization and force timing systems into holdover mode, where performance depends on the quality of the clock. For critical infrastructure, that risk is unacceptable. A stronger, independent timing solution is needed.

Our solution

Temporal Photonics offers a compact, highly accurate and robust clock designed for long holdover time in a handheld system. Built on years of experience in semiconductor processing and integrated photonics, our technology delivers reliable timing without the need of a daily GPS or GNSS signal.

Key benefits

• Operational in GPS/GNSS denied environments.

• Optical atomic clock performance in a compact form factor.

• Small size for easy deployment (e.g. mobile or ad hoc networks).

• Long holdover for resilient timing in demanding environments.

Why it matters

A small robust and accurate clock allows GNSS-free positioning and navigation solutions which open the next generation of navigation technologies.

Moreover, a mesh network of ad hoc synchronized clocks will reduce dependence on GNSS and thus improve network resilience.

The path forward

Temporal Photonics is advancing compact, accurate clocks that strengthen the resilience of modern networks. By reducing reliance on external timing signals, we help to synchronize critical systems, secure, and operational when it matters most.
