Problems solved by technology
[0004] However, users who often use the GPS global positioning system are not familiar with the destination. If the surrounding environment of the destination is complicated or the map information of the GPS global positioning system is not updated in time and the specific location of the destination cannot be displayed, the GPS global positioning system cannot play a role. The role of navigation and positioning cannot fully meet the needs of users

Embodiment Construction
[0019] Please refer to figure 1 , is a block diagram of a navigation and positioning system 1000 . The navigation and positioning system 1000 runs on the server 100 and multiple electronic devices with navigation and positioning functions, and is executed by the processors of the server 100 and multiple electronic devices with navigation and positioning functions. Wherein the server 100 is the server 100 of the GPS global positioning system, and there is a user database 120 in the server 100, and the registration information of all registered users is stored in the user database 120; the electronic device is specifically the first electronic device 200 , multiple second electronic devices 300 and other electronic devices with navigation and positioning functions. The first electronic device 200 is an electronic device used by a user who initiates a directions request, and can initiate a directions request. The second electronic device 300 is an electronic device used by the ...

The invention provides a navigation positioning system. The navigation positioning system works on a server, as well as a plurality of first electronic devices and second electronic devices, which have navigation positioning functions. The navigation positioning method comprises the following steps: the first electronic devices receive a user's operation to generate search request information and send the information to the server; the server searches a user's database according to the search request information and sends a search result to the first electronic device; and the first electronic devices respond to the user's choice operation, determine the user, receive the user's editing operation to generate asking direction request information, send the asking direction request information to the determined user through the server, and also can receive asking direction reply information by the server. The electronic device and the navigation method and system thereof, provided by the invention, aim to ask users, who are familiar with the current location, the direction information through information exchange when the current environment is so complex that the specific location on an electronic map can not be displayed.
Description
technical field [0001] The invention relates to an electronic device and its navigation and positioning method and system, in particular to an electronic device capable of realizing navigation mutual assistance and its navigation and positioning method and system. Background technique [0002] GPS (Navigation Satellite Timing and Ranging / Global Positioning System acronym NAVSTAR / GPS abbreviation) global positioning system was developed by the United States in the 1970s and was fully completed in 1994. It has positioning in sea, land and air. A new generation of satellite positioning and navigation system capable of implementing three-dimensional navigation in all directions. [0003] Using the GPS global positioning system can realize map query, route planning, automatic navigation, voice navigation, screen navigation, re-planning routes, etc. It is widely used, with high speed and timing accuracy, fast time-saving and high efficiency. There are also more and more products,...
