Time synchronisation modules ensure continuous uptime for critical infrastructure such as data centres, telecom, financial institutions, satlink stations and more<\/strong><\/p>\n\n\n\n

Precise time synchronisation is the backbone of today’s connected world, keeping telecom networks, data centers, and financial systems running seamlessly. Without accurate timing, our digital infrastructure would quickly fall out of sync.<\/p>\n\n\n\n

The Septentrio mosaic-T timing module delivers nanosecond-level precision for synchronization and is trusted by companies such as Meinberg, Viavi, and Saab. Built-in\u00a0AIM+<\/strong><\/a>\u00a0technology protects against intentional and unintentional Global Navigation Satellite System (GNSS)<\/strong> jamming and spoofing, ensuring maximum system uptime even in challenging or hostile conditions. Regular participation in live jamming and spoofing events, such as the Jammertest in Norway, ensures Septentrio receivers remain at the forefront of resilience innovation. The next-generation\u00a0mosaic-G5 T<\/strong><\/a>\u00a0module continues this legacy, offering high precision and exceptional resilience in an ultra-compact form factor.<\/p>\n\n\n\n

Rising threats to GNSS integrity: safeguarding critical timing systems<\/strong><\/p>\n\n\n\n

Incidents of GNSS interference are increasing worldwide. Airports in Eastern Europe have experienced GNSS disruptions that caused rerouting, delays, and potential safety hazards. But the impact extends far beyond aviation. When GNSS timing is compromised, the effects can cascade through telecom networks, power grids, and financial systems.<\/p>\n\n\n\n

The UK’s Knowledge Transfer Network warned that organised criminals could spoof financial institutions’ clocks, manipulate trading timestamps, and then revert them to conceal fraudulent transactions.<\/p>\n\n\n\n

These trends highlight that GNSS interference and spoofing pose systemic risks to critical infrastructure making robust and resilient timing references indispensable.<\/p>\n\n\n\n

Industry-trusted timing: AIM+ technology powering global leaders<\/strong><\/p>\n\n\n\n

Driven by decades of expertise in GNSS timing and reinforced by\u00a0AIM+<\/strong><\/a>\u00a0Advanced Interference Mitigation technology, Septentrio modules set the standard for precision and reliability\u2014trusted by leading players in the timing industry.<\/p>\n\n\n\n

VIAVI Solutions<\/strong>\u00a0is another global leader providing Assured PNT solutions to safeguard critical operations for businesses, governments, and infrastructure providers. Their\u00a0timing and frequency systems<\/strong><\/a>\u00a0maintain nanosecond precision even under RF interference, leveraging Septentrio mosaic for assured accuracy.<\/p>\n\n\n\n

Meinberg<\/strong>\u00a0is a manufacturer of high-precision time and frequency synchronisation systems \u2014 including GNSS time servers\u2014used in critical infrastructure, telecom, and industrial networks. Meinberg integrates Septentrio’s multi-constellation, multi-frequency GNSS module, mosaic-T, as the timing engine inside its high-resilience products. In combination with AtomiChron technology, Meinberg achieves unmatched spoofing resilience with authentication across all four major GNSS constellations.<\/p>\n\n\n\n

Saab<\/strong>\u00a0integrated Septentrio receivers in their Air Traffic Management system to synchronize their\u00a0Multilateration and ADS-B surveillance<\/a><\/strong>.\u00a0To validate GNSS resilience Saab also took these receivers to the Jammertest, find out more in this\u00a0customer story<\/strong><\/a>.<\/p>\n\n\n\n

Spoofing awareness and protection for critical infrastructure<\/strong><\/p>\n\n\n\n

GNSS spoofing is a cyberattack in which false satellite signals mislead a receiver into producing the wrong time. For timing receivers, this can disrupt entire networks. Because critical infrastructure depends on precise GNSS time, its static nature makes it particularly vulnerable to GNSS spoofing attacks.<\/p>\n\n\n\n

Spoofing attacks can vary in type and sophistication. A cleverly set-up ‘pull-away’ attack gradually changes the time and can bypass built-in system-level software checks. Luckily sophisticated GNSS receivers have advanced technology, such as AIM+ to flag and prevent spoofing at the core signal-processing level, maintaining reliable time integrity.<\/p>\n\n\n\n

Since the receiver is at the forefront of signal tracking and reception, interference detection and protection at the receiver core is essential to prevent GNSS spoofing from corrupting downstream systems. Septentrio’s approach combines multiple defensive that work in synergy to detect and mitigate GNSS spoofing.<\/p>\n\n\n\n
