LEA-F9T module u-blox F9 high accuracy timing module

Multi-band GNSS receiver with nanosecond-level timing accuracy

Meets the most stringent 5G timing requirements

Ideal for global deployments due to configurable L1/L2/E5b and L1/L5/E5a multiband operation

Unaffected by ionospheric errors

Differential timing mode for highly accurate local timing

Built-in security for highest robustness against malicious attacks

Extended −40 °C to +105 °C temperature range for superior reliability in challenging environments

The LEA-F9T timing modules provide nanosecond-level timing accuracy to the most demanding infrastructure applications.

LEA-F9T is designed to meet the most stringent timing synchronization requirements in 5G mobile networks on a global scale. By significantly reducing the time error of the primary source of cellular network synchronization, the LEAF9T will help operators maximize the performance of their networks and so optimize the return on their investment in 5G communications.

The timing module’s multi-band capability reduces the timing error under clear skies to less than 5 ns without the need for an external GNSS correction service. To further improve accuracy locally, the LEA-F9T features a differential timing mode that exchanges correction data with other neighboring GNSS timing receivers via a communication network.

LEA-F9T timing modules are pin-compatible with previous generations allowing ready migration from earlier designs. The extended temperature range and sulfur resistant components provide superior reliability even in compact urban 5G installations.

Multi-band access to all four global satellite constellations with support for L1/L2/E5b and L1/L5/E5a frequency bands strengthens the receiver's capability for delivering more reliable performance.

LEA-F9T includes advanced security features such as secure boot, secure interfaces, and T-RAIM to provide the highest level timing integrity. 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.

u-blox modules use GNSS chips qualified according to AEC-Q100, are manufactured in ISO/TS 16949 certified sites, and are fully tested on a system level. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
