Safran's Timing Milestone Signals New Urgency in GPS-Denied Warfare

ROCHESTER, NY – June 01, 2026 – Safran Federal Systems, a key mission partner for the U.S. Department of Defense, has announced the delivery of its 50,000th SecureSync™ time synchronization system. While the number marks a significant manufacturing milestone, it also casts a spotlight on an increasingly vital and vulnerable aspect of modern society: the invisible, non-stop stream of timing data that underpins everything from national defense to the global financial system.

The achievement underscores the growing reliance on Assured Positioning, Navigation, and Timing (A-PNT) solutions in an era where the Global Positioning System (GPS) is no longer an infallible guarantee. As threats from jamming and spoofing escalate, the demand for resilient systems like SecureSync, which can maintain precise time even when GPS signals are attacked or unavailable, has become a cornerstone of national security strategy.

The Invisible Battle for Time

Precision timing is the silent, unsung hero of the digital age. It enables secure communications, coordinates power grids, time-stamps financial transactions, and guides military assets. However, the vast majority of these systems rely on the faint, easily disrupted signals broadcast by GPS satellites. This dependency has created a critical vulnerability that state and non-state actors are increasingly exploiting.

• Jamming, the act of overpowering GPS signals with noise, can create "no-go" zones for navigation and timing.
• Spoofing, a far more insidious threat, involves broadcasting counterfeit signals to trick receivers into calculating a false position or time. The increasing availability of sophisticated Software-Defined Radios (SDRs) has made spoofing attacks a tangible threat to commercial aviation, shipping, and military operations.

The consequences of losing reliable time can be catastrophic. In a defense context, a fraction of a second can mean the difference between a successful mission and a catastrophic failure. "Our solutions are in the field, actively supporting warfighters, and we remain as committed as ever to delivering the reliability that missions depend on," said Trevor Dougherty, Vice President of Sales and Marketing at Safran Federal Systems, in a recent statement. "In an environment where a fraction of a second can mean the difference between success and failure, we don't just deliver precise time — we make it resilient.” This resilience is the core value proposition of modern A-PNT systems, which are designed to detect, mitigate, and provide alternatives to compromised GPS signals.

A Versatile Guardian for Defense and Infrastructure

The widespread adoption of SecureSync is a testament to its modular and versatile design. The platform is not only a fixture in highly secure military environments but also a critical component in civilian infrastructure. Over 90% of U.S. 911 call centers, for instance, rely on Safran's timing technology to ensure coordinated emergency responses.

Its success stems from a multi-layered approach to resilience. The system can pull timing data from multiple GNSS constellations (GPS, Galileo, GLONASS, BeiDou) and incorporates various internal precision oscillators—from standard crystals to highly stable Rubidium atomic clocks—that can maintain accurate time for extended periods during a signal outage, a capability known as holdover.

For military applications, SecureSync's support for the encrypted, jam-resistant M-Code signal is paramount. M-Code provides authorized military users with a more robust and secure PNT signal, ensuring operational continuity in electronically contested environments. The system's ruggedized chassis is built to meet military environmental standards (MIL-STD-810F), making it suitable for deployment across all domains—land, air, and sea. This dual-use capability, protecting both the warfighter and the homeland's critical infrastructure, highlights the converging need for trustworthy timing across all sectors of national importance.

The Future Frontier: Picoseconds and Quantum Clocks

While the 50,000th SecureSync unit marks a major achievement, Safran is already focused on the next generation of timing technology, where the battle for precision will be fought at the quantum and picosecond level. The company is actively investing in two key areas that promise to revolutionize A-PNT.

The first is White Rabbit, an open-standard technology born out of CERN, the European Organization for Nuclear Research. It leverages standard Ethernet networking to synchronize thousands of devices with picosecond-level precision—a thousand times more accurate than a nanosecond. For defense, this could enable new capabilities like highly distributed radar arrays that act as a single, cohesive sensor and even more secure, frequency-hopping communication systems.

Even more transformative is the company's work in quantum timing. Quantum sensors and clocks operate by measuring the fundamental properties of atoms, providing a source of PNT that is completely independent of external signals like GPS. This technology holds the key to true navigation and timing assurance in environments where GPS is permanently denied, such as underwater or deep underground. Through programs like DARPA's Robust Quantum Sensor (RoQS) initiative and strategic collaborations with quantum technology firms like Infleqtion, Safran is developing miniaturized quantum devices that could one day be integrated into everything from individual soldier systems to hypersonic missiles.

This forward-looking investment signals a strategic understanding that the race for PNT superiority is relentless. As adversaries develop more sophisticated methods to disrupt GPS, the development of resilient, multi-layered, and ultimately GPS-independent timing solutions is not just an engineering challenge—it is a national security imperative. The journey from the first timing device to the 50,000th SecureSync reflects a half-century of innovation, but the push toward quantum horizons shows the mission to secure time is just beginning.
