Abstract

The invention discloses a target terminal positioning method, device, storage medium and electronic equipment. Wherein, the method includes: responding to a positioning request triggered by the target terminal, acquiring target ephemeris information and target base station information, wherein the target ephemeris information includes ephemeris information of a target satellite used to locate the target terminal, and the target base station information includes Based on the signal information generated by the target base station for locating the target terminal; based on the target ephemeris information and the approximate location information of the target terminal, the pseudo-range observation value is obtained; based on the elevation information corresponding to the pseudo-range observation value and the approximate location, the approximate location Correction is performed to obtain the target position where the target terminal is located. The present invention solves the technical problem of low positioning accuracy of target terminals, and can be applied to scenarios such as map navigation, high-precision maps, positioning, and automatic driving and unmanned driving in the field of artificial intelligence.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a target terminal positioning method, device, storage medium and electronic equipment. Background technique [0002] In recent years, the application of terminal positioning has become more and more extensive, but in the existing technology, it is often necessary to use communication base stations for positioning, but because the positioning accuracy of base stations is related to the density of base station deployment, for example: in some urban areas, the density of base station deployment is about several Only one base station can be deployed within ten kilometers, and the density of base stations in some townships is even lower, so the location accuracy obtained based on base station information is at the kilometer level; in the case of weak satellite signals, if WIFI or GNSS positioning is not on time, When only using the base station for positioning, it is difficult to meet...
