Navigation applications are increasingly demanding in automation, as well as functionality and safety. From intelligent connected vehicles to autonomous driving, unmanned aerial vehicles, etc., all need to support of high-precision positioning technology.

In recent years, automated driving technology gradually to market , to mass production, it is dependent on the high precision positioning technology. Beidou high-precision positioning technology can avoid the interference of external factors. Even in bad weather or under the coverage of weak satellite signals from other on-board sensors, it can still provide accurate, stable and reliable positioning information for autonomous driving vehicles, help the vehicle to judge the current position, and carry out the overall cognition of the road environment, so as to facilitate the vehicle to make the next decision.  

Under the condition of the indoors, in tunnel, urban canyon, there are  limitations to realize high precision positioning, however, such as unmanned application requirements to ensure navigation data continuity and accuracy.
