The invention provides a navigation method and device. The navigation method comprises the following steps: a voice message input by a user is acquired and analyzed semantically; if a semantic analysis result shows that information input by the user contains destination information and a navigation task triggering instruction, a navigation route is obtained according to the destination information a and the current location information of the user; navigation is performed according to the navigation route, wherein during navigation based on the navigation route, when the condition that the distance between the location of the user and a preset location on the navigation route is smaller than a preset distance is detected, a brief route prompt message is displayed on a screen and broadcasted through voice. The navigation method and device have the advantages of simple operation and concise interface, the driving safety during navigation can be improved, the user experience can be improved, and the product stickiness is enhanced.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a navigation method and device. Background technique [0002] GPS (Global Positioning System, Global Positioning System) is composed of 24 working satellites, which are located in the sky above 20200km (kilometers) from the earth's surface, evenly distributed on 6 orbital planes (4 on each orbital plane), and the orbital inclination is 55° °. In addition, there are 4 active backup satellites in orbit. The distribution of satellites makes it possible to observe more than 4 satellites anywhere in the world at any time, and can maintain a geometric image with good positioning resolution accuracy. This provides continuous global navigation capability in time. [0003] In GPS observation, the distance from the satellite to the receiver can be accurately known from the position of the satellite, and then using the distance formula in the three-dimensional coordinat...
