Making ADAS available in dense urban areas can only be solved through a combination of advanced systems all working together.
Cities are chaotic. Constant vertical and density growth means that GNSS is continually challenged due to satellite signals being obscured or reflected.
A GNSS system that is capable of determining absolute location even in these areas, where satellite signal reflection has previously made it impossible, will be a key enabler in the race towards full autonomy.
S-GNSS unlocks the full potential of ADAS in urban environments by resolving the long-standing GPS barriers caused by multipath interference and the risk of intentional disruption from spoofing.
Overall confidence in vehicle positioning is elevated, improving integrity and enhancing cyber-security.
Unlocking the full potential of ADAS
Introducing S–GNSS Auto®
S-GNSS Auto® resolves long term technical barriers to the future of vehicle autonomy.
S-GNSS determines the angle of arrival of incoming signals using software-based processing, without the need for any hardware changes.
This enables S-GNSS to attenuate undesirable signals such as reflections. spoofers and jammers.

We can help you resolve your GNSS challenges, as we create the future for autonomous vehicle positioning.
Our collaboration with GM is focusing on possible applications of Supercorrelation technology in future vehicles, including enhancements and expansion of it's Super Cruise advanced hands-free driving assistance technology.
GM has investigated several approaches to mitigate multipath effects in dense urban areas, including integration of GNSS with additional sensors like cameras, wheel odometry, or precise point positioning corrections. S-GNSS entails a simplified systems engineering design to achieve consistent accuracy.
