Quick Start

In this guide we'll cover how to setup the ZED-X20P GNSS breakout board. To follow along with this tutorial, at a minimum, users will need the following items:

• Computer with an operating system (OS) that is compatible with all the software installation requirements
• USB 3.1 Cable A to C - 3 Foot - Used to interface with the ZED-X20P GNSS Breakout (1)
• SparkFun Allband GNSS RTK Breakout - ZED-X20P (Qwiic)

1. If your computer doesn't have a USB-A slot, then choose an appropriate cable or adapter.

USB Programming

The USB connection is utilized for configuration and communication with the ZED-X20P GNSS module. Users only need to connect their ZED-X20P GNSS breakout board to a computer using a USB-C cable.

External Antenna

In order to receive GNSS signals, users will need to connect a compatible antenna.

Tip

For the best performance, we recommend users choose a compatible L1/L2/L5/L-band GNSS antenna and utilize a low-loss cable. Also, don't forget that GNSS signals are fairly weak and can't penetrate buildings or dense vegetation. The GNSS antenna should have an unobstructed view of the sky.

u-center 2 Software

u-center 2 is u-blox's software application for configuration, evaluation, and debugging of u-blox GNSS receivers and services. The software provides a relatively, simple graphics user interface to assess and test u-blox GNSS modules for navigation and positioning performance. It also allows users to define or apply GNSS product configurations for specific use cases. Saving, restoring, or sharing configurations between different products is easy.

Installation

Installation of the u-center 2 software is straight forward; simply, click on the button below to download the software. User should be aware that the first time the software accessed, they will need to either create or login to their existing u-blox account. If necessary, users can follow the video below or reference the user manual for more instructions.
