Cooperation with Israel’s Autotalks, which is leading the expansion of V2X
'V2X-Enhanced GNSS' guarantees the security, accuracy, and reliability of location information

STMicroelectronics (ST) and Autotalks, an Israeli company that pioneered the V2X chipset market and is leading the early expansion of V2X, announced that they have combined GNSS technology with V2X communication technology.

The new 'V2X-Enhanced GNSS' ensures safe and certified vehicle positioning, enabling highly accurate and stable location information determination, particularly on urban roads, tunnels, and parking garages. Accurately measuring absolute and relative positions with respect to other vehicles or infrastructure is essential for the advancement of semi-autonomous and fully autonomous vehicles.


The V2X-enhanced GNSS developed by Autotalks and ST is based on the world-class V2X chipset previously jointly developed and successfully developed by the two companies. This chipset connected vehicle-to-vehicle and vehicle-to-infrastructure within wireless range for safety and mobility applications. The efficiency, maneuverability, and safe driving of autonomous vehicles are possible only through accurate location information, which can be achieved through the convergence of V2X technology and GNSS.

Hagai Zyss, CEO of Autotalks, stated, “For autonomous driving, safety, accuracy, and security must all be treated equally, and no driver would compromise on any of them.” He added, “Our solution was designed from the ground up for the implementation of automated driving. Recognizing the critical importance of localization in autonomous vehicles, Autotalks and ST have continuously strived to optimize accurate V2X localization. We believe our customers will also understand this value and potential.”

When V2X-enhanced GNSS technology operates with V2X-supported infrastructure, it transmits an absolute position to the vehicle that can determine lane-level accuracy. This precision is used not only to enhance navigation capabilities on urban roads and tunnels, but also to develop many new applications, such as autonomous parking and identification of available spaces in roads and garages.

Antonio Radaelli, Senior Vice President of Automotive Digital and Infotainment at ST, said, “To fully realize the security, convenience, and other benefits of autonomous driving, safe, stable, and accurate communication between the vehicle and its surroundings must be ensured. This allows for precise identification of surrounding conditions, such as how close objects are, where the vehicle is going, or whether there is road construction or an accident ahead.” He added, “Building on our successful collaboration with Autotalks, we have been able to smoothly transition to a safe, accurate, and stable V2X-enhanced GNSS era by integrating ST’s advanced positioning technology and roadmap for satellite-certified high-precision automotive GNSS with Autotalks’ advanced signal-processing algorithms.”

In 2016, field testing is being conducted in an Asian country under the supervision of a government agency to test this technology.
