Adtran has launched new synchronization solutions that incorporate Satellite Time and Location (STL) technology to address the growing vulnerabilities of GPS and other GNSS systems to jamming and spoofing attacks.

One of these solutions is the OSA 5405-S PTP grandmaster clock, which now has the capability to receive STL signals alongside GNSS-based timing. This versatile device can be deployed both indoors and outdoors, making it suitable for a wide range of industries including 5G, data centers, smart grids, and defense.

Another offering from Adtran’s Oscilloquartz suite is the OSA 5400 STL module, which allows third-party switches and servers to benefit from a compact STL/GNSS receiver. STL utilizes low-earth orbit (LEO) satellites as a reliable and secure time source, offering an effective alternative to GNSS.

This dual-source approach aligns with zero-trust principles, ensuring resilience even in the event of GNSS disruption. It addresses the critical need for timing resilience in light of the increasing vulnerabilities faced by GNSS systems.

The OSA 5405-S supports both LEO time services and multi-constellation GNSS, among other timing sources. By leveraging the power of STL signals, it can provide highly precise positioning, navigation, and timing (PNT) services even in GNSS-denied environments. This makes it a vital resource for mobile operators, power utility companies, government agencies, and scientific research.

The OSA 5400 STL module also incorporates STL receiver technology and enhances synchronization resilience in challenging conditions.

Adtran’s collaboration with Satelles and the integration of STL technology into their products demonstrates their forward-thinking approach in addressing synchronization challenges and anticipating future industry needs.

STL technology offers superior reach and provides an added layer of resiliency and precision, particularly in indoor environments. It strengthens synchronization network infrastructure and offers simplicity, security, and cost-effectiveness in installations.

Overall, Adtran’s new synchronization solutions with STL technology provide reliable and secure alternatives to GNSS-based timing, ensuring the resilience of critical infrastructure.
