U-blox has expanded its automotive GNSS portfolio with the introduction of the ZED-X20K and ZED-A20K modules. The two modules support the autonomy roadmap from ADAS L2+ to L4. Both feature pin-to-pin compatibility, jamming and spoofing detection, and are designed to reduce complexity, cost, and integration effort for OEMs and Tier 1 suppliers.
The ZED-X20K targets mass-market ADAS L2+/L3 and TCU/IVI applications. It provides lane-level accuracy worldwide using all-band GNSS and native Galileo High Accuracy Service (HAS), without requiring paid correction services, backend infrastructure, or service management.
The ZED-A20K is designed for safety-critical L3/L4 systems. It delivers ISO 26262 ASIL-B(D)-compliant GNSS RAW data alongside high-performance QM positioning outputs in a single module, enabling a transition from dual-GNSS architectures. It offers flexible support for externally hosted positioning engines, particularly for software-defined vehicle architectures.
The form-factor compatibility between the modules allows different vehicle trim levels to be equipped from a single socket depending on functional safety requirements. Andreas Thiel, CEO of u-blox, stated that the modules address automotive localization needs across the autonomy roadmap. The ZED-X20K has reached the Engineering Sample stage with an evaluation kit available. Samples of the ZED-A20K will be available from August 2026.
