SparkFun GNSS-RTK Accessory Kit

Description Attachments

The SparkFun GNSS-RTK Accessory Kit is the ultimate set for those who value precision in their navigation systems. The kit is designed to enhance the accuracy of GPS, GLONASS, Galileo, and BeiDou constellation modules to millimeter precision. It includes a GNSS multiband antenna, a ground plate, and a reversible USB-A to USB-C cable.

The ANN-MB-00 GNSS multiband antenna included in the kit is a standout feature. Unlike other GNSS/GPS antennas, it is designed to receive both the classic L1 GPS band and the newer L2 GPS band. This antenna is built to withstand the harshest environments, thanks to its robust construction and magnetic base with additional mounting holes. It's designed for the latest u-blox F9 platform, including the ZED-F9P module, but can be used with any GPS/GNSS receiver that can benefit from the L1/L2 dual reception.

The antenna supports GPS, GLONASS, Galileo, and BeiDou and includes a high-performance multi-band RHCP dual-feed patch antenna element, a built-in high-gain LNA with SAW pre-filtering, and a 5m SMA cable.

Another highlight of this kit is the ground plate. It significantly enhances the performance of GPS and GNSS antennas, making it an ideal solution for those who want to use an antenna not on a car or other large metallic objects.

Completing the kit is a reversible USB-A to USB-C cable. This 0.8-meter cable supports USB 2.0 speeds and charging up to 2A, making it perfect for embedded enthusiasts who need the flexibility of a thinner cable and the convenience of a reversible USB-C & USB-A connection.
