The ZED-F9T Module from u-blox is a Multi-band GNSS receiver with nanosecond-level timing accuracy. This GNSS module meets the most stringent timing synchronization requirements in 5G mobile networks on a global scale. The timing module’s multi-band capability 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. To further improve accuracy locally, the ZED-F9T features differential timing modes that exchange correction data with other neighboring GNSS timing receivers via a communication network.
The ZED-F9T aims also to address concerns regarding the integrity and resilience of GNSS-based timing synchronization solutions for critical infrastructure applications. The module 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 that means the module has the ability to concurrently receive multi-band signals from America’s GPS, Europe’s Galileo, Russia’s GLONASS, and China’s Beidou satellites.
