Abstract

The invention discloses a target terminal positioning method and device, a storage medium and electronic equipment. The method comprises the steps of responding to a positioning request triggered by a target terminal, and acquiring target ephemeris information and target base station information, wherein the target ephemeris information comprises ephemeris information of a target satellite used for positioning the target terminal, and the target base station information comprises signal information generated by the target base station used for positioning the target terminal; obtaining a pseudo-range observation value based on the target ephemeris information and the approximate position information of the target terminal; and correcting the approximate position based on the pseudo-range observation value and the elevation information corresponding to the approximate position to obtain a target position where the target terminal is located. The technical problem that the positioning accuracy of the target terminal is low is solved, and the method can be applied to automatic driving, unmanned driving and other scenes in the fields of map navigation, high-precision maps, positioning and 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...
