u-blox offers a new, compact dual-band timing module that provides nanosecond-level timing accuracy, meeting the stringent timing necessities for 5G communications. The new NEO-F10T complies with the company's NEO form factor (12.2mm x 16mm), permitting space-constrained designs to be realised without compromising size.

The NEO-F10T is the successor to the NEO-M8T module, offering an easy upgrade path to dual-band timing technology. This enables NEO-M8T users to access nanosecond-level timing accuracy and enhanced security.

Its dual-band technology mitigates ionospheric errors and significantly reduces timing errors without needing an external GNSS correction service. Also, when within the operational area of an SBAS, it offers the possibility to enhance the timing performance by utilising the ionospheric corrections supplied by the SBAS system. As the device supports all four global satellite constellations and L1/L5/E5a configuration, it greatly simplifies global deployments as the same device can be employed universally.

The device incorporates advanced security features, including secure boot, secure interfaces, configuration lock, and T-RAIM to supply the highest-level timing integrity. This provides that reliable, uninterrupted service is delivered, as any attempt to interfere with the receiver is unlikely to be successful. Further, advanced anti-jamming and anti-spoofing algorithms are incorporated to enhance security still further.

The module includes a single RF input for all the GNSS bands and dual SAW filters for superior signal selectivity and out-of-band attenuation. It is compatible with the company's ANN-MB1 L1/L5 multi-band antenna, making it easy to evaluate the performance of the timing modules. The devices function from a single 2.7V to 3.6V supply and draw only 19mA (@ 3V) throughout continuous operation.

"NEO-F10T is designed to meet the timing synchronisation requirements in 5G small cells and private networks on a global scale. By significantly reducing the time error of cellular network synchronisation, the NEO‑F10T module will help operators maximise the performance of their networks, and so optimise the return on their investment in 5G communications," says Samuli Pietila, director of Product Line Management, Timing and Infrastructure, at u-blox.
