U-blox has expanded its automotive GNSS portfolio with the launch of two highly specialized modules: the ZED-X20K and the ZED-A20K. This dual release addresses engineering needs of both mass-market advanced driver assistance systems (ADAS) and safety-critical autonomous architectures.
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.
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 stage, and its evaluation kit is available. Samples for the ZED-A20K will be available starting in August.
