Abstract

The invention discloses a locating method and an electronic device. A locating request is sent to a base station, so that available satellite list information of the base station is received, and predicted navigational satellite broadcasting data are obtained; according to an available satellite list, a satellite to be detected currently is determined, and a GPS navigation message played by the satellite to be detected currently is detected; when the assigned length of the GPS navigation message played by the satellite to be detected currently is received, the first GPS time corresponding to the GPS navigation message with the assigned length is determined according to the predicted navigational satellite broadcasting data; the first GPS time is used, so that the pseudo-range corresponding to the satellite to be detected currently is calculated; when the pseudo-ranges of the available satellites of the assigned number are calculated, the position information of the electronic device is determined according to the calculated pseudo-ranges. Consumed time for locating the electronic device can be shortened through the locating method.

Description

technical field [0001] The present invention relates to the technical field of equipment positioning, and more specifically relates to a positioning method and electronic equipment. Background technique [0002] GPS positioning technology is widely used in various fields. At present, the position information of the electronic device can be relatively accurately located by using the GPS positioning technology. [0003] The process of positioning an electronic device using GPS positioning technology is generally to send a positioning request to a base station through the electronic device, and the base station sends a list of available satellites to the electronic device. The electronic device searches for satellites according to the list of available satellites, buffers the navigation message from the searched satellites, detects the synchronization signal in the navigation message, and obtains the GPS time from the navigation message after the synchronization signal, so as ...
