Abstract

The invention discloses a positioning method. The positioning method comprises the following steps of receiving first information which is sent by a first electronic device and generated by a second electronic device, wherein the first information is not smaller than a first threshold value number and is not shorter than the time of a second threshold value; receiving second information transmitted by the second electronic device in real time, wherein the second information is not smaller than the first threshold value number; the state that the duration for receiving the second information reaches the duration of a third threshold value, calculating the duration generated for receiving the second information of the second electronic device, wherein the second information is not smaller than the first threshold value number; according to the duration, calculating the distance from the second electronic device which is not smaller than the first threshold value number; when the number of the distance of the second electronic device which is calculated is confirmed to be not smaller than the first threshold value number, transmitting the distance which is not smaller than the first threshold value number and is calculated to the first electronic device; receiving the distance which is sent by the first electronic device and is not smaller than the first threshold value number to determine position information of electronic equipment. The invention also discloses the electronic equipment. According to the positioning method and the electronic equipment provided by the embodiment of the invention, the positioning speed is increased, and the positioning duration is reduced.

Description

technical field [0001] The invention relates to positioning technology, in particular 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 to use the GPS time to calculate pseudorange,...
