The typical positional accuracy provided by standalone GNSS is 3-10 meters, which is suitable for automotive applications such as navigation and emergency call. With the emergence of high precision GNSS, able to mitigate the influence of errors, sub-decimeter positional accuracy is possible and it becomes usable for more advanced applications such as C-V2X and autonomous driving. Naturally, to be applicable for these safety-critical applications, other preconditions such as availability and data integrity must also be met.
