u-Blox unveils GNSS precision timing module for 5G


u-blox’s ZED-F9T aims to address the concerns of integrity and resilience of GNSS-based timing synchronization solutions for critical infrastructure applications

GNSS time is already used by the previous generation of cellular networks for synchronization, but better synchronization throughout the network will be a key enabler for 5G. The 5G celluar network will need stringent coordination to provide much greater bandwidth and a broader range of services to the users than 4G, supporting features like support sophisticated features such as beam-forming, carrier aggregation, and massive MIMO.


u-blox has released the ZED-F9T high accuracy timing module that meets even the most stringent timing synchronization requirements in 5G mobile networks on a global scale.

ZED-F9T has multi-band capability which allows it to compensate the ionosphere error from all GNSS satellite constellations and reduce the timing error under clear skies to less than five nanoseconds without the need for an external GNSS correction service. And access to all four satellite constellations strengthens the receiver’s global coverage and increases timing availability in challenging signal environments, ultimately delivering more reliable performance.

Key Features of ZED-F9T

  • ZED-F9T features differential timing modes that exchange correction data with other neighboring GNSS timing receivers via a communication network
  • ZED-F9T includes advanced security features such as secure boot, secure interfaces, and Time-Receiver Autonomous Integrity Monitoring (T-RAIM) to provide highest level timing integrity
  • ZED-F9T’s support for all four GNSS constellations enables developers to design single products to serve global markets, simplifying OEMs’ product lines
  • The module has a single RF input for all the GNSS bands, which simplifies antenna selection
  • An on-board diplexer, followed by dual SAW filters, provides exceptional signal selectivity and out-of-band attenuation
  • Offered in a 54-pin land grid array package of just 17.0 x 22.0 x 2.4mm, it is designed for easy integration.

“The ZED-F9T’s nanosecond-level timing accuracy meets the most stringent requirements for 5G networks on a global scale. By significantly reducing the time error of the primary source of cellular network synchronization, the ZED-F9T will help operators maximize the performance of their networks and so optimize the return on their investment in 5G,” says Samuli Pietila, Principal Product Management, Product Center Positioning at u-blox.

“The ZED-F9T aims also to address concerns regarding the integrity and resilience of GNSS-based timing synchronization solutions for critical infrastructure applications,” Pietila adds. “The ZED-F9T will give network operators the capabilities to achieve unmatched immunity against spoofing and jamming attacks by combining concurrent reception of four GNSS satellite constellations with multi-band signal reception,” he adds, referring to the module’s ability to concurrently receive multi-band signals from America’s GPS, Europe’s Galileo, Russia’s GLONASS, and China’s Beidou satellites.
