Adtran has launched new synchronization solutions featuring Satellite Time and Location (STL) technology to address the growing vulnerabilities of GPS and other GNSS systems to jamming and spoofing attacks.
STL harnesses low-earth orbit (LEO) satellites as a distinct time source, offering an alternative to GNSS. This dual-source approach aligns with zero-trust principles, ensuring resilience even in the event of GNSS disruption.
Adtran’s OSA 5405-S PTP grandmaster clock can now receive STL signals alongside GNSS-based timing. The device caters to a diverse range of indoor and outdoor deployment settings, serving industries from 5G and data centers to smart grids and defense. The OSA 5400 STL module, which brings the benefits of a compact STL/GNSS receiver to third-party switches and servers, is also available from the Adtran Oscilloquartz suite.
The OSA 5405-S supports both LEO time services and multi-constellation GNSS, among other timing sources. By leveraging the power of STL signals, which are up to 1,000 times stronger and significantly more secure than GNSS, it can penetrate even the most challenging environments, including deep inside buildings and other hard-to-reach locations.
“The world is waking up to the need for timing resilience. As GNSS systems face increasing vulnerabilities, it’s clear that relying solely on traditional synchronization sources is a ticking time bomb for our critical infrastructure. The potential fallout could be massive: grounded flights, non-functioning power plants and financial systems thrown into chaos. That’s why the launch of our OSA 5405-S is so crucial. With this solution, we’re making jamming and spoofing nearly impossible,” said Gil Biran, GM of Oscilloquartz, Adtran. “By ensuring highly precise positioning, navigation and timing (PNT) services even in GNSS-denied applications, our OSA 5405-S will be a vital resource for mobile operators, power utility companies, government, scientific research and more.”
