SparkFun GNSS-RTK Accessory Kit

SparkFun GNSS-RTK Accessory Kit is designed for dialing the accuracy of the GPS, GLONASS, Galileo, and BeiDou constellation modules to just millimeters. This kit includes a GNSS multi-band antenna designed to receive both the classic L1 and L2 GPS bands. The antenna 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. This GNSS-RTK Accessory Kit also includes a ground plate, which significantly increases the performance of GPS and GNSS antennas. The GNSS-RTK Accessory Kit features a reversible USB-A connector and 5m coaxial cable with an SMA connector.

The items in the kit are irreversible USB-A to USB-C cables. 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 and USB-A connection. This cable has the D+/D- wires alongside large-gauge VBUS/GND wires.
