The typical positional accuracy supplied by standalone GNSS is 3-10 meters, which is appropriate for automotive functions resembling navigation and emergency name. With the emergence of excessive precision GNSS, in a position to mitigate the affect of errors, sub-decimeter positional accuracy is feasible and it turns into usable for extra superior functions resembling C-V2X and autonomous driving. Naturally, to be relevant for these safety-critical functions, different preconditions resembling availability and knowledge integrity should even be met.
This poster exhibits the several types of error sources and explains how excessive precision GNSS calculates and transmits error correction knowledge to automobiles, enabling new automotive functions for GNSS.
