SparkFun GNSS-RTK Accessory Kit

With GNSS you are able to know where you are, where you're going, and how to get there anywhere on Earth within 30 seconds. This means the higher the accuracy the better! GNSS Real Time Kinematics (RTK) has mastered dialing in the accuracy of their GPS, GLONASS, Galileo, and BeiDou constellation modules to just millimeters. The SparkFun GNSS-RTK Accessory Kit gives you just what you need to start using your RTK board for your project.

Included in this kit is a GNSS multiband antenna. The ANN-MB-00 GNSS multiband antenna is extremely unique from other GNSS/GPS antennas in that it is designed to receive both the classic L1 GPS band and the newly launched (started in 2005) L2 GPS band. Additionally, the ANN-MB-00 from u-blox is extremely well built with both a magnetic base with mounting holes for additional anchoring for the harshest environments.

Designed for the latest u-blox F9 platform--including the ZED-F9P module--it provides a fast, easy, and reliable multi-band antenna solution but can be used with any GPS/GNSS receiver that can benefit from the L1/L2 dual reception.

This 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.

Also included in this kit is a ground plate. Many magnetic mount GPS antennas rely on being mounted on a car or other large metallic object to provide a good ground plane. But what if you want to use an antenna not on a car? The GPS Antenna Ground Plate is the solution! This plate significantly increases the performance of GPS and GNSS antennas.

To round off the included items in this kit is a reversible USB-A to USB-C cable. Supporting USB 2.0 speeds and charging up to 2A, this 0.8 meter cable is perfect for embedded enthusiasts that need the flexibility of a thinner cable and the wonderful feel of a reversible USB-C & USB-A connection. The 0.8m/~2ft length is perfect in small applications.

This cable has the D+/D- wires alongside large-gauge VBUS/GND wires. Rated for 2A, we've successfully pulled 2A@5V with minimal voltage drop. If you're looking for a full USB-C implementation checkout our USB 3.1 cable.
