SparkFun Allband GNSS RTK Breakout - ZED-X20P (Qwiic)

SparkFun Allband GNSS RTK Breakout - ZED-X20P (Qwiic) (GPS-28871)

The SparkFun All-band GNSS RTK Breakout - ZED-X20P (Qwiic) features the latest GNSS engine from u-blox; the X20, which is a successor to their popular F9 engine. This board's dimensions, pin layout, and connectors are very similar to the SparkFun GPS-RTK-SMA Breakout - ZED-F9P (Qwiic); and in most circumstances, can be used as a drop-in replacement. The board also accommodates users with a diverse choice of interfaces including USB, UART, SPI, and I²C.

The ZED-X20P module is an all-band, high precision GNSS receiver that concurrently processes signals from the GPS, Galileo, BeiDou, QZSS, and NavIC constellations across all GNSS frequency bands, including L-band. With positioning algorithms for Real-time Kinematics (RTK), PPP-RTK, and Precise Point Positioning* (PPP) technologies, the module supports standard RTCM corrections for Virtual Reference Stations (VRS) in a Network RTK setup or a local base station setup. Additionally, L-band correction services are natively supported without the need to integrate an external receiver, such as the NEO-D9S.

With its very high update rate, the ZED-X20P module is ideal for control applications, ensuring smooth and reliable operation. The module also protects system integrity with multi-layered defenses, including a Root of Trust, jamming and spoofing detection, cryptographic authentication of navigation messages through Galileo OSNMA, and more. This represents the highest level of integration in a single-chip receiver for the navigation and robotics markets; in unmanned autonomous vehicles (UAVs), guidance systems, and auto-steering applications.

The ZED-X20P module is supported by the u-blox u-center 2 GNSS software for real-time performance analysis, receiver configuration, and data logging. The AssistNow Online, Offline, and Autonomous A-GNSS services can also be used with the module for faster satellite acquisition. Users can also interface with the GNSS module using NMEA 4.11 and UBX binary protocols.

Note

The USB interface does not fully comply with industry standards and is not suitable for production use. The USB 2.0 FS (full speed, 12 Mbit/s) interface can be used for host communication. Due to the hardware implementation, it may not be possible to certify the USB interface.
