u-blox expands automotive GNSS portfolio enabling ADAS at a global scale
u-blox has announced the expansion of its automotive GNSS portfolio with the launch of two highly specialised modules: the ZED-X20K and the ZED-A20K. Both modules feature pin-to-pin compatibility, enabling platform flexibility and simplifying product development across vehicle generations as well as jamming and spoofing detection to mitigate the impact of security risks.
As automakers scale their autonomy strategies, they face diverging localisation challenges. Engineering teams deploying ADAS L2+ systems require scalable, high-accuracy positioning that works globally without the burden of paid or fragmented regional correction services. At the same time, safety architects developing L3 and L4 platforms require high-integrity positioning and are often forced to rely on complex dual-GNSS architectures to meet stringent functional safety requirements.
To address these needs, u-blox introduces two purpose-built solutions. The ZED-X20K is designed for mass-market ADAS L3 and TCU/IVI applications, delivering lane-level accuracy worldwide using all-band GNSS and native Galileo High Accuracy Service (HAS). By eliminating the need for paid correction services, backend infrastructure, or service management, it reduces total cost and accelerates time-to-market while maintaining consistent global performance.
For applications that require a functional-safety concept for GNSS sensors, the ZED-A20K introduces a new architectural approach. It provides ISO 26262 ASIL-B(D)-compliant GNSS RAW data simultaneously to high-performance QM positioning outputs within a single module. This enables OEMs to transition from traditional dual hardware based-GNSS systems to a single module approach, reducing system complexity and cost. With flexible support of externally hosted positioning engines, especially for ADAS of Levels 3 and up, the A20 concept enables enhanced flexibility for SDV–based architectures. The form-factor compatibility between ZED-X20K and ZED-A20K allows the flexibility to equip different trim levels with or without functional safety requirements out of a single socket.
The ZED-X20K has reached the Engineering Sample (ES) stage, and its evaluation kit is available. Samples for the ZED-A20K will be available from August 2026.
