Multi-band GNSS Receiver to Bring Nanosecond Timing Accuracy to 5G Networks

Oscilloquartz, a company of ADVA Optical Networking, has launched the first 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. 

This new multi-band GNSS receiver is a major milestone for network synchronization. For the first time, operators can harness a solution with multi-band GNSS capabilities combined with Oscilloquartz's core devices, which can deliver line rates up to 10Gbit/s and support ePRTC levels of timing accuracy. Their modular technology offers a way to enhance equipment in the field, achieve PRTC-B levels of timing and improve the timing accuracy of ePRTC. All that’s required is a simple antenna upgrade. Then the multi-band solution can be plugged into the available slot of OSA 5430 or OSA 5440 for the nanosecond accuracy that will be key to the services of tomorrow. And, as enhanced availability is also essential for emerging applications, the new technology features unrivalled jamming and spoofing detection capabilities combined with centralized AI-powered GNSS assurance suite.

The new multi-band GNSS receiver has been officially launched at International Timing and Sync Forum (ITSF) event and can be viewed on Oscilloquartz’s stand between November 4 and 7.
