German company ADVA launched a modular multi-band Global Navigation Satellite Signal (GNSS) receiver for ePRTC and PRTC-B synchronization, bringing new levels of precision timing to 5G networks.  The new solution is engineered to overcome ionospheric delay variation that causes timing inaccuracy, enabling communication service providers (CSPs) and enterprises to deliver nanosecond precision.  Previously, this was achieved with expensive, rubidium clocks.  Now, there’s a simple and highly cost-effective way to upgrade installed synchronization infrastructure for unprecedented accuracy and reliability.  

The multi-band, multi-constellation GNSS receiver card plugs into ADVA’s OSA 5430 and OSA 5440, advanced core grandmaster clocks able to support PTP, NTP and SyncE over multiple 1Gbit/s and 10Gbit/s Ethernet interfaces.  This enables network operators to meet the requirements of the ITU’s stringent PRTC-B specifications and support the most advanced 5G applications.
