What precision navigation is needed for l3-l5 level to realize automatic driving?

L3-l5 autopilot requires flying songs, with smooth navigation and accurate navigation. Moreover, the high-precision positioning module of Beidou enhanced base station can achieve sub-meter and centimeter-level positioning accuracy; In indoor positioning and navigation technology, the positioning accuracy of Bluetooth positioning technology is 3~5m, and the positioning and navigation accuracy of UWB technology can reach centimeter level.

Main advantages:

At present, positioning terminals, including mobile phones, use their own major navigation systems and multi-system fusion positioning, so the positioning accuracy does not depend on which navigation system is used. In fact, several major systems will be used.

On the terminal side, some special positioning and navigation devices for fishing have higher positioning accuracy, and if commercial positioning signals paid for are superimposed (compared with free civil positioning signals), the positioning accuracy is higher.
