u-blox NEO-F10T dual-band GNSS timing module

u-blox has announced a compact dual-band timing module that has been designed to offer nanosecond-level timing accuracy, thereby meeting the stringent timing requirements for 5G communications. The NEO-F10T is compliant with the u-blox NEO form factor (12.2 x 16 mm), allowing space-constrained designs to be realised without the need to compromise on size.

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

u-blox’s dual-band technology is designed to mitigate ionospheric errors and reduce timing error, without the need of an external GNSS correction service. Additionally, when within the operational area of a satellite-based augmentation system (SBAS), the module offers the possibility to improve the timing performance by using the ionospheric corrections provided by the SBAS system. As the product supports all four global satellite constellations and L1/L5/E5a configuration, it simplifies global deployments as the same device can be used universally.

The module includes advanced security features such as secure boot, secure interfaces, configuration lock and T-RAIM to provide high-level timing integrity. This means that uninterrupted service is delivered as any attempt to interfere with the receiver is unlikely to be successful. Additionally, advanced anti-jamming and anti-spoofing algorithms are included to further enhance security.

The module has a single RF input for all the GNSS bands and dual SAW filters for good signal selectivity and out-of-band attenuation. It is compatible with u-blox’s ANN-MB1 L1/L5 multi-band antenna, making it simple to evaluate the performance of the timing modules. The devices operate from a single 2.7 to 3.6 V supply and draw just 19 mA (@3 V) during continuous operation.

The product is designed to meet the timing synchronisation requirements in 5G small cells and private networks on a global scale. By reducing the time error of cellular network synchronisation, the module will help operators maximise the performance of their networks and so optimise the return on their investment in 5G communications.
