Unlock centimetre-level positioning with full tilt compensation using the SparkPNT ZED-X20P & IM19 GNSS Flex Module. This is one of our most advanced modules in the GNSS Flex series, combining the ZED-X20P all-band RTK GNSS receiver with the high-precision IM19 IMU for accurate navigation in the most demanding 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 the GNSS receiver, as well as dedicated UARTs for the IMU.
At the core of the Module is the u-blox ZED-X20P, a professional-grade, all-band GNSS receiver that delivers centimetre-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.
Paired with the ZED-X20P is the Feyman (FMI) IM19 IMU, which combines MEMS sensor data with the GNSS RTK positioning data to provide high-precision attitude measurements. This enables advanced features, like tilt-compensated surveying and robust navigation through brief GNSS outages.
Survey-Grade Accuracy: Delivers roll and pitch measurements accurate to within 0.05 degrees.
Tilt Compensation: No more perfectly vertical survey poles! The IM19 can calculate a virtual digital level point at any tilt angle, revolutionizing field data collection.
Sensor Fusion: Offers a continuous navigation solution (Dead Reckoning) even during brief GNSS signal loss, making it ideal for urban or obstructed environments.
This GNSS Flex Module has been designed for the ZED-X20P and IM19 to work in symbiosis. By default, the ZED-X20P's navigation data is automatically fed to the IMU. The IM19 then outputs proprietary NMEA messages containing the fully compensated position and attitude (roll, pitch, and yaw). This default link can be easily reconfigured via onboard jumpers to suit your specific project needs.
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 utilised. 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.
