Abstract

The embodiment of the invention provides a terminal equipment positioning method and device, the terminal equipment and a storage medium, which relate to a navigation positioning technology, and can be applied to the fields of map navigation, automatic driving, intelligent transportation and the like. The Terminal equipment positioning method comprises the following steps of determining an approximate position of the terminal equipment, sending the approximate position of the terminal equipment to the CORS system, and receiving satellite observation data of at least one reference station sentby the CORS system based on the approximate position of the terminal equipment, and calibrating the approximate position of the terminal equipment according to the satellite observation data of the atleast one reference station and the satellite observation data of the terminal equipment to obtain the accurate position of the terminal equipment. According to the embodiment of the invention, the problem of low positioning accuracy of the terminal equipment in the prior art is solved, and the GNSS first positioning time of the terminal equipment can be effectively shortened, so that the map navigation positioning precision is improved, lane-level navigation is assisted, and the user experience is optimized.

Description

technical field [0001] The present application relates to the technical field of navigation and positioning, and in particular, the present application relates to a terminal device positioning method, device, terminal device, and storage medium. Background technique [0002] With the rapid development of electronic navigation and positioning technology, more and more terminal devices with navigation and positioning functions can help users accurately locate the current location as the starting point, and provide users with navigation routes according to the destination entered by the user. In this way, the user is assisted to reach the destination. [0003] At present, the positioning function in navigation mainly relies on the global navigation satellite system GNSS (the Global Navigation Satellite System), for example, the global satellite navigation system includes GPS (Global Positioning System, Global Positioning System), BDS (BeiDou Navigation Satellite System, system...
