The SparkFun Allband 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); in most circumstances, it can be used as a drop-in replacement. The board also accommodates users with diverse 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. L-band correction services are natively supported without integrating an external receiver, such as the NEO-D9S.
With its exceptionally 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 and in unmanned autonomous vehicles (UAVs), guidance systems, and auto-steering applications.
Note: The USB interface does not fully comply with industry standards and is unsuitable 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, certifying the USB interface may not be possible.
