The everyday positional accuracy supplied by standalone GNSS is 3-10 meters, which is appropriate for automotive functions reminiscent of navigation and emergency name. With the emergence of excessive precision GNSS, capable of mitigate the affect of errors, sub-decimeter positional accuracy is feasible and it turns into usable for extra superior functions reminiscent of C-V2X and autonomous driving. Naturally, to be relevant for these safety-critical functions, different preconditions reminiscent of availability and knowledge integrity should even be met.

This poster exhibits the various kinds of error sources and explains how excessive precision GNSS calculates and transmits error correction knowledge to automobiles, enabling new automotive functions for GNSS.
