Embodiment 1

[0022] The terminal positioning method is applicable to various mobile terminals, such as mobile phones, notebook computers, tablet computers, vehicle-mounted computers and the like. The execution subject of this embodiment is a terminal positioning device. figure 1 It is a schematic flowchart of a terminal positioning method according to Embodiment 1 of the present invention, as shown in figure 1 As shown, the terminal positioning method in this embodiment includes:

[0023] Step 101, the first terminal acquires information of each first satellite through GPS.

[0024] The first terminal can be a mobile phone, a notebook computer, a tablet computer, a vehicle-mounted computer, etc. The first terminal obtains satellite information through GPS, and the satellite information includes: the number of the satellite, the three-dimensional coordinates of the satellite, the distance from the satellite to the first terminal, and the second The time difference between a terminal recei...

Embodiment 2

[0043] This embodiment provides a terminal positioning method based on the first embodiment. figure 2 It is a schematic flow chart of a terminal positioning method according to Embodiment 2 of the present invention, such as figure 2 As shown, the terminal positioning method includes:

[0044] In step 201, the first terminal judges whether the information of the currently searched first satellite sent by the second terminal is acquired.

[0045]Specifically, the currently searched satellite sent by the second terminal is divided into two types, the satellite with the same number as the satellite searched by the first terminal is called the first satellite, and the satellite with a different number from the satellite searched by the first terminal called the second satellite. In this step, the first terminal needs to judge whether the currently searched satellite with the same number as the first satellite searched by the first terminal sent by the second terminal has been o...

Embodiment 3

[0071] This embodiment provides a further supplementary description of the terminal positioning method in the above embodiment, image 3 It is a schematic flowchart of a terminal positioning method according to Embodiment 3 of the present invention, as shown in image 3 As shown, the terminal positioning method also includes:

[0072] In step 301, the first terminal receives a satellite information acquisition request sent by a third terminal, and the satellite acquisition request includes the acquired satellite serial number sent by the third terminal.

[0073] Specifically, the third terminal may be a mobile phone, a notebook computer, a tablet computer, a vehicle-mounted computer, and the like. The first terminal receives the satellite information acquisition request sent by the third terminal, and the satellite request includes the serial number of the satellite that the third terminal has acquired. The first terminal and the third terminal may be the same or different. ...

Abstract

The invention provides a terminal positioning method and a device. The method comprises the following steps: acquiring the information of each first satellite by a first terminal through a GPS (Global Positioning System); if the quantity of the first satellites searched by the first terminal within a preset time is less than a preset threshold value, acquiring the information, presently searched by a second terminal which is sent by the second terminal, of each second satellite by the first terminal, wherein the serial number of each first satellite is different from the serial number of each second satellite; judging whether the sum of the quantity of the first satellites and the quantity of the second satellites is more than or equal to the preset threshold value; if yes, positioning the first terminal by the first terminal according to the information of each first satellite and the information of each second satellite. According to the terminal positioning method and the device provided by the invention, the quick terminal positioning is realized under the condition of the inexistence of WiFi (Wireless fidelity) and ephemeris data.

Description

technical field [0001] The present invention relates to terminal positioning technology, in particular to a terminal positioning method and device. Background technique [0002] With the development of smart technology, the use of Global Positioning System (GPS) positioning is becoming more and more useful. Many functions of mobile terminals are carried out under the condition of determining the location of the user, such as Weibo, WeChat , map tools, taxi tools, etc. [0003] Currently, there are many assisted GPS positioning systems on the market, such as utilizing Wireless-Fidelity (WiFi for short), ephemeris data, etc. to realize fast GPS positioning. Although location can be determined by assisted GPS positioning systems, in many cases this assisted mode cannot be used. For example, a group of mountaineering enthusiasts lost their way in the mountains. At this time, it is very important to obtain the geographic information in time. However, without WiFi and ephemeris ...
