u-blox ZED-X20P All-Band High Precision GNSS Modules

u-blox ZED-X20P All-Band High Precision GNSS Modules integrate all-band GNSS with signal modernization and innovative positioning algorithms using Real-time Kinematics (RTK), PPP-RTK, and Precise Point Positioning (PPP) technologies in a compact, energy-efficient form factor. The u-blox ZED-X20P concurrently processes signals from the GPS, Galileo, BeiDou, QZSS, and NavIC constellations across all GNSS bands, including the L-band. The high level of integration on a single-chip receiver enables new system architectures and creates value for industrial navigation and robotics markets in products such as unmanned autonomous vehicles (UAVs), guidance systems, and auto-steering applications.

With a very high update rate, the ZED-X20P module is ideal for control applications, ensuring smooth and reliable operation. For advanced users, pristine raw data features minimal cycle slips and exceptionally low noise in carrier range and pseudo-range measurements. ZED-X20P protects system integrity with multi-layered defenses, including a Root of Trust, jamming/spoofing detection, cryptographic authentication of navigation messages through Galileo OSNMA, and more. High-value, application-specific features such as a moving baseline are also available.

The receiver enables easy integration, helping product developers bring ideas to market quickly. ZED-X20P natively supports a range of correction services, striking the perfect balance between performance and data usage. It supports standard RTCM corrections for Virtual Reference Stations (VRS) in a Network RTK or a local base station setup. SPARTN-format SSR correction service broadcasts are also supported for mass-market applications, and direct reception of PPP global services simplifies deployments.
