u-blox announces secure high-precision dual-band GNSS timing module

u-blox has unveiled a compact dual-band timing module that offers nanosecond-level timing accuracy, meeting the stringent timing requirements for 5G communications.

The NEO-F10T is compliant with the u-blox NEO form factor (12.2x16 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 upgrade path to dual-band timing technology. This allows NEO-M8T users to access nanosecond-level timing accuracy and enhanced security.

u-blox’s dual-band technology mitigates ionospheric errors and greatly reduces timing error, without the need of an external GNSS correction service. Additionally, when within the operational area of a Satellite Based Augmentation System (SBAS), NEO-F10T offers the possibility to improve the timing performance by using the ionospheric corrections provided by the SBAS system.

As the NEO-F10T supports all four global satellite constellations and L1/L5/E5a configuration, it significantly simplifies global deployments as the same device can be used universally.

NEO-F10T includes advanced security features such as secure boot, secure interfaces, configuration lock, and T-RAIM to provide the highest-level timing integrity. This ensures that reliable, uninterrupted service is delivered as any attempt to interfere with the receiver is unlikely to be successful.

In addition, 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 exceptional 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 V to 3.6 V supply and draw just 19 mA (@ 3.0 V) during continuous operation.
