Abstract

The invention discloses a positioning method, device, system and storage medium. The method includes: receiving the first location information sent by the terminal; the first location information includes the identity of the terminal; sending a differential data request to the second server, the differential data request includes the first location information, and the differential data request is used for the second server to determine The differential data of the terminal; receive the differential data sent by the second server; calculate the first position information according to the differential data to obtain the second position information; send the second position information to the terminal, and quickly return the terminal positioning result, so that the terminal can determine The network delay is greatly reduced when the location is accurate.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a positioning method, device, system and storage medium. Background technique [0002] In the process of automatic driving, the high-precision positioning of the vehicle is the first element to ensure the driving safety of the vehicle. [0003] At present, the high-precision positioning technology is mainly based on the "cloud + terminal" positioning mode. The "cloud + terminal" positioning mode includes cloud servers and satellite positioning terminals. Further, the differential positioning result of the satellite positioning terminal is determined, and fed back to the satellite positioning terminal. [0004] However, the communication between the cloud server and the satellite positioning terminal in the "cloud + terminal" positioning mode will cause a large network delay. Contents of the invention [0005] Embodiments of the present invention provide a po...
