SparkFun GPS-RTK-SMA Kit

Standard GPS gives you location data within a few meters. Real-Time Kinematics (RTK) dials that accuracy down to the millimetre. The SparkFun GPS-RTK-SMA Kit is the complete, all-in-one GNSS package, designed to get you up and running with professional-grade, high-precision positioning right away.

With this kit, we’ve taken the guesswork out of hardware selection. We've paired our tried-and-true ZED-F9P Breakout with a reliable Multi-Band L1/L2 Antenna, a robust Ground Plate, and the necessary cabling. Whether you need Rover or Base modes, this kit contains everything you need to achieve 10mm accuracy right out of the box.

What's Inside the Kit?

GPS-RTK-SMA Breakout (ZED-F9P)

At the heart of this kit is the brains of the operation, the u-blox ZED-F9P Module. This powerhouse receiver can simultaneously receive GPS, GLONASS, Galileo, and BeiDou. By utilising both the L1 and L2 frequency bands, it corrects for ionospheric errors and delivers three-dimensional accuracy to within roughly the width of your fingernail.

• Rover & Base: Can operate as a Rover (receiving corrections) or a Base Station (broadcasting corrections).
• SMA Connector: Features a robust, industry-standard SMA connector for a secure antenna connection.
• Qwiic & USB: Connects easily via USB-C or the solderless Qwiic ecosystem.
• Backup Battery: An on-board rechargeable battery ensures fast "warm starts" (two-second time-to-first-fix).

GNSS Multi-Band Magnetic Mount Antenna

A high-precision receiver is useless without the right antenna. We’ve included a high-quality, Multi-Band (L1/L2/L5) active antenna specifically designed to capture the signals the ZED-F9P needs. It features a magnetic base for easy mounting to vehicle roofs or the included ground plate.

GPS Antenna Ground Plate

Antenna performance is heavily dependent on having a proper ground plane. We’ve included a heavy, 4-inch-diameter, 1/16-inch-thick steel ground plate. This simple addition significantly improves signal reception and multi-path rejection, ensuring you get the best possible performance from your antenna.

Easy Integration & Software

The ZED-F9P is incredibly configurable (Geofencing, variable update rates up to 20Hz, etc.), but we've made it easy to use.

• No Soldering Required: With the included Qwiic connectors and USB cable, you can hook everything up without touching a soldering iron.
• Leave NMEA Behind: We’ve written an extensive SparkFun Arduino library for u-blox modules that uses the lightweight binary interface (UBX) to read latitude, longitude, heading, and speed over I²C, saving your microcontroller's serial port for other tasks.

So stop guessing which antenna pairs with which receiver. With the SparkFun GPS-RTK-SMA Kit, we've done the heavy lifting of component selection for you. This kit provides a verified, professional-grade signal chain right out of the box.
