Adtran, in partnership with Iridium Communications Inc. announced the European and Asia-Pacific launch of its synchronization solutions featuring Iridium®? Satellite Time and Location (STL) technology, a significant step in countering growing threats to Global Navigation Satellite Systems (GNSS). Adtran's OSA 5405-S PTP compact grandmaster clock with STL capabilities and its OSA 5400 STL module are now available to timing network operators in Western Europe, major countries in Eastern Europe, Turkey, and parts of Asia-Pacific, including the majority of Southeast Asia, Japan and South Korea.

The solutions enhance the resilience and reliability of critical infrastructure, such as 5G networks, defense systems and many more. Leveraging low-Earth orbit (LEO) satellites to deliver precise and secure positioning, navigation and timing (PNT) services, the devices ensure continuous synchronization even in environments where GNSS is compromised. As a certified Iridium partner, Adtran offers the technology through two distinct purchasing options: an annual service license for optimal flexibility or bundled with equipment for long-term financial planning.

Iridium®? STL services harness the power of LEO satellites to transmit encrypted signals that are 1,000 times stronger than those of GNSS, significantly reducing vulnerability to disruptions and manipulation. The technology excels in challenging environments like urban canyons and indoor areas and can penetrate deep into buildings without the need for rooftop antennas.

STL is a powerful solution for fortifying zero-trust architecture and ensuring reliable PNT even whenPS signals fail, making it ideal for both indoor and challenging outdoor locations. By empowering operators of mission-critical networks to access reliable timing in the most demanding environments, we're also eliminating the need to install outdoor antennas and core through concrete, significantly reducing expenses.
