Problems solved by technology

[0002] In the current car navigator industry, due to the diversification of products, there are many models. The current vehicle navigation mainly depends on the GPS positioning system. It must receive four or more effective satellite signals at the same time to be correct. Locate the position of the vehicle, and navigation cannot be realized without GPS signals. For example, when the vehicle moves between tunnels and high-rise buildings in the city, the vehicle-mounted GPS navigation system will not be able to navigate and locate due to the attenuation of satellite signals

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] In the traditional vehicle positioning method, the terminal receives satellite signals through the GPS positioning system, and realizes vehicle positioning according to the satellite signals. When the terminal is in a tunnel, indoors or between high-rise buildings in the city, the GPS positioning system will not be able to navigate due to the attenuation of satellite signals position.
