It's a special Thursday here at SparkFun Electronics because today we are adding a new GNSS RTK board to the ranks. Introducing the SparkFun Triband GNSS RTK Breakout! Built in collaboration with our newest partners at Septentrio, this board features the highly-accurate and low-power mosaic-X5 GNSS module. This is a basic breakout board that was designed to get you started as quickly and as easily as possible. In fact, to operate it you won't even have to write a single line of code if you don't want to! Let's take a closer look, shall we?

We see new iterations with GNSS each passing year, and with the SparkFun mosaic-X5 Triband GNSS RTK Breakout, you'll be provided with the easiest way to start using L1, L2, and L5 bands simultaneously! At the heart of the Triband GNSS RTK Breakout is Septentrio's most compact high-precision GNSS receiver, the mosaic-X5. The mosaic-X5 module is an ultra-low power, multi-band, multi-constellation GNSS receiver capable of delivering centimeter-level precision at high update rates. The receiver supports the GPS (USA), GLONASS (Russia), Beidou (China), Galileo (Europe), and NavIC (India) constellations, including regional systems (i.e. SBAS and QZSS). It also features Septentrio's unique AIM+ technology for interference mitigation and anti-spoofing, ensuring best-in-class reliability and scalable position accuracy.

With its Real Time Kinematics (RTK) capabilities, the mosaic-X5 module can operate as a base station to broadcast RTK correction data or as a rover utilizing RTK correction data to record positions with extreme precision. The module can achieve a horizontal accuracy of 6mm (~0.25in), vertical accuracy of 1cm (~0.4in) using RTK, and timing precision of 5ns (5 billionths of a second). The mosaic-X5 is compatible with RTK correction data from various 3rd-party services. The mosaic-X5 can also deliver position updates at 100Hz (100 times per second) for automotive and industrial applications.

The mosaic-X5 is a sophisticated chip running an internal web server that can be accessed through the USB interface with a standard browser using a Linux/Windows computer. Septentrio also provides dozens of video tutorials to guide users through the configuration settings of their GNSS receivers utilizing the web interface. In addition to the module's web interface, Septentrio provides software packages where users can post-process recorded data, configure the mosaic-X5 module, and analyze the receiver's performance or the GNSS signals for interference/spoofing. If these interface options weren't enough, Septentrio's GNSS modules are compatible with other 3rd-party software packages.

Beyond the capabilities of the mosaic-X5 module, this board is seamless to operate with no programming skills required. Gone are the times when a microcontroller was required to interface with the GNSS receiver and log data to an SD card and when users had to carry around an SD card reader to extract the data from the SD card. The mosaic-X5 Triband GNSS RTK Breakout can start/stop logging data at the push of a button. The same button can also mount and unmount the SD card to your computer through the USB interface. Users can control/configure the module, log data, etc., all without a single line of code. For the users who prefer a command-line interface, Septentrio has you covered. Users can still control and configure the mosaic-X5 module through a CLI, which is useful for scenarios such as production line testing.

Get Started with the mosaic-X5 Tri-band GNSS RTK Breakout Guide

We've even written a complete guide that will help you begin working with the mosaic-X5 Triband GNSS RTK Breakout! By clicking the image or button above you will be able to learn about any extra parts you'll need to get up and running, a full hardware overview and assembly, and how to get you started with software. This guide is a fantastic launching point for the breakout, so make sure you check it out as well!

And that's it for today! The mosaic-X5 Triband GNSS RTK Breakout is now available to order. We expect this board to sell out pretty fast, so if we happen to sell out, don't worry, we're busy building more!

Thank you so much for stopping by today and taking a look at our newest GNSS board. We'll see you tomorrow to take a look at the rest of this week's new products (including a video for this board as well)! Happy hacking!
