The SparkFun GNSS Timing Breakout is a specialised tool designed for applications where time is just as critical as position. Featuring the u-blox ZED-F9T-20B GNSS receiver, this board offers an impressive five nanoseconds of timing accuracy under clear skies without requiring any external GNSS correction data. Whether you are maximizing the efficiency of a 5G IoT network, synchronising a distributed sensor grid, or building a high-precision NTP server, this breakout provides the ultra-accurate time reference you need.
The ZED-F9T-20B is a top-of-the-line multi-band module that supports L1, L2/L5, and E5a/E5b bands across major constellations (GPS / QZSS, Galileo, BeiDou, and NavIC). By tracking multiple bands concurrently, the ZED-F9T-20B ensures extreme versatility and timing stability, even if it loses lock with one or more specific constellations.
The ZED-F9T-20B also features native support for Galileo OSNMA (Open Service Navigation Message Authentication), which protects against spoofing by verifying the authenticity of GNSS data.
We designed this breakout to be a complete GNSS development tool, even borrowing the form factor of our popular GPS-RTK-SMA line to give you every connection you need:
To ensure your system is up and running quickly, the breakout includes an onboard rechargeable backup battery. This powers the module's internal Real Time Clock (RTC), drastically reducing the Time-To-First-Fix from a cold start (~24 seconds) to a hot start (~2 seconds).
