What map does 58 use in the same city?

Beidou satellite navigation map is used in the same city.

Beidou satellite navigation system (hereinafter referred to as Beidou system) is a satellite navigation system independently built and operated by China with an eye to the needs of national security and economic and social development. It is an important national space infrastructure, providing all-weather, all-day and high-precision positioning, navigation and timing services for global users.

With the development of Beidou system construction and service capacity, related products have been widely used in transportation, marine fishery, hydrological monitoring, weather forecasting, surveying and mapping geographic information, forest fire prevention, communication timing, power dispatching, emergency rescue and emergency search and rescue. And gradually penetrate into all aspects of human social production and people's lives, injecting new vitality into global economic and social development.

Beidou system has the following characteristics:

Firstly, the space segment of Beidou system adopts a mixed constellation composed of three kinds of orbiting satellites. Compared with other satellite navigation systems, there are more high-orbit satellites with stronger anti-occlusion ability, especially in low latitudes.

Secondly, Beidou system provides navigation signals with multiple frequency points, and the service accuracy can be improved through the joint use of multi-frequency signals.

Thirdly, Beidou system innovatively integrates navigation and communication capabilities, and has five functions: real-time navigation, quick positioning, accurate timing, position reporting and short message communication service.
