Precision timing and reference frequency

Global Navigation Satellite Systems (GNSS), such as GPS, Galileo, and BeiDou, provide highly accurate timing signals. By embedding precise timestamps from on-board atomic clocks in their broadcasts, these satellites enable geographically dispersed equipment to synchronize with Coordinated Universal Time (UTC) down to a few nanoseconds. This capability extends beyond positioning alone: GNSS signals are commonly leveraged to generate stable reference frequencies (within parts per billion), ensuring that time-sensitive processes remain aligned, consistent, and traceable.

Precision timing is essential wherever small timing errors can have outsized consequences. By capitalizing on GNSS timing, it becomes possible to establish reliable, cost-effective, and globally consistent clocks that power next-generation services and applications.

Security

For over 20 years, u-blox has been safeguarding time synchronization, constantly redefining what it means to deliver reliability and precision. GNSS-based systems in critical infrastructure must be protected from spoofing, jamming, and other adversarial techniques. Even minor timing offsets can trigger cascading failures in these high-stakes environments, making secure GNSS solutions paramount.

Our timing solutions embed multiple layers of protection to ensure signal and device integrity. Advanced anti-spoofing features, along with dual output and jamming detection backed by active mitigation, allow continuous monitoring and immediate counteraction against rogue signals. A built-in spectrum analyzer and support for Galileo OSNMA further reinforce signal authenticity.

On the device side, secure boot, secure firmware updates, and configuration locks protect against unauthorized modifications, while a secure interface enables reliable receiver message authentication.

Redundancy is also key: multi-band and multi-constellation support help maintain precise timing even when GNSS signals are compromised. By combining robust security with proven reliability, our solutions meet the most stringent 5G timing requirements, as well as the needs of today’s most demanding applications.
