SparkFun Triband GNSS RTK Breakout - mosaic-X5

SparkFun's mosaic-X5 Triband GNSS RTK Breakout offers a seamless way to leverage the power of L1, L2, and L5 GNSS bands simultaneously. At its core, the compact and high-precision mosaic-X5 receiver from Septentrio delivers centimeter-level accuracy at high update rates. It supports multiple constellations including GPS, GLONASS, Beidou, Galileo, and NavIC, and features AIM+ technology for interference mitigation and anti-spoofing.

With Real Time Kinematics (RTK) capabilities, the module can function as a base station broadcasting RTK correction data or as a rover utilizing this data for pinpoint accuracy. It achieves a horizontal accuracy of 6mm, vertical accuracy of 1cm, and timing precision of 5ns. The mosaic-X5 can deliver position updates at 100Hz, making it ideal for automotive and industrial applications.

The mosaic-X5 integrates an internal web server accessible via USB with a standard browser on Linux or Windows. Septentrio offers extensive video tutorials to guide users through configuration settings. Additionally, software packages are available for post-processing data, configuring the module, and analyzing GNSS signals for interference or spoofing. Compatibility with third-party software packages adds to its versatility.

No programming skills are required to operate this board. Users can start/stop data logging with a button press and mount/unmount the SD card via the USB interface. For those who prefer a command-line interface, the module can be controlled and configured through a CLI, which is useful for production line testing.

This breakout board is perfect for projects requiring the integration of the mosaic-X5 module with access to most of its pins, similar to Septentrio's developer kit but in a smaller form factor. Whether you need a PPS output at a 3.3V logic level or other advanced features, this board has you covered. For more detailed information, refer to the features tab and the hookup guide.
