How high positioning accuracy can gps vehicle positioning achieve with high energy?

Hello, here are my answers. If I can help you, I hope I can adopt. thank you

Take F9k module used in the field of intelligent driving as an example. The module can receive the signals of four GNSS constellations at the same time, but the positioning accuracy below the meter level cannot be achieved only by the signals of four GNSS constellations. Therefore, ublox integrates multi-frequency RTK technology and F9 GNSS technology platform for F9k module, and achieves decimeter positioning accuracy for automobiles in a short convergence time.

The positioning products used for mobile phone positioning and car positioning are different. For example, Xiaomi 8 can achieve a positioning accuracy of 3-5 meters after using dual-frequency GPS. Compared with F9 positioning module with stable performance and multi-frequency GNSS technology, the positioning accuracy of mobile phone is not as good as that of vehicle navigation and positioning carried by ublox series products.
