For use in Australia

Operate only in bands and with settings that are permitted for your location and application. Check this product’s supported frequencies in the description/specs.
If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation.

For use in other regions

Follow the spectrum rules for your country/region and select frequencies and settings accordingly.

A declaration of use will need to be submitted during checkout.

Achieve centimeter-level positioning with the next generation of high-precision GNSS using the SparkPNT ZED-X20P GNSS Flex Module. This module features the latest u-blox X20 engine, the powerful successor to the popular F9 engine, making it the ideal choice for demanding navigation and control applications.

Like all SparkPNT GNSS Flex Modules, this board is designed to be easily swappable and pin-compatible for future upgrades. It connects to your GNSS Flex pHAT carrier board via standardized 2x10-pin headers, which break out the module’s set of interfaces, including USB (See USB note), dual UARTs, and I²C for seamless integration into your Raspberry Pi or similar single-board computer (SBC).

X20P Marks the Spot

At the core of the Module is the u-blox ZED-X20P, a professional-grade, all-band GNSS receiver that delivers centimeter-level accuracy. It concurrently processes signals from all major constellations (GPS, Galileo, BeiDou, etc.) across all frequency bands, including L-band, providing incredibly fast and reliable fixes for control applications like UAVs, guidance systems, and auto-steering.

RTK & PPP Ready: Supports Real-time Kinematics (RTK), PPP-RTK, and Precise Point Positioning* for ultimate flexibility.
L-Band Corrections: Natively supports L-band correction services*, eliminating the need for external receivers.
High Update Rate: Ensures smooth and reliable operation in high-speed robotics and vehicle control systems.
Uncompromising Security: Features multi-layered defenses including a Root of Trust, advanced jamming and spoofing detection, and Galileo OSNMA cryptographic authentication.

This product requires an external antenna and a GNSS Flex carrier board. Users should have two options for connecting an external GNSS antenna to their GNSS receiver.

The GNSS Flex Module has a U.FL connector for an external antenna.
For a sturdier connection, an SMA connector on a GNSS Flex pHAT carrier board can be utilized. Users can simply jumper the U.FL connectors between the SparkPNT GNSS Flex Module and the carrier board with a short U.FL cable.

*According to u-blox, support for Precise Point Positioning (PPP) and full L-band correction services is still under development and will be made available through a future firmware update.
