Positioning method, mobile terminal and terminal system

Abstract

The invention discloses a positioning method, mobile terminal and terminal system. According to the positioning method, two mobile terminals are utilized to perform positioning, wherein one of the mobile terminals is a master machine, and the other mobile terminal is a slave machine, wherein the slave machine stores the exact value of the current position of the slave machine as a first accurate value. The positioning method comprises the following steps that: S1, the master machine obtains the satellite positioning value of the current position of the master machine through a satellite used by primary positioning and adopts the satellite positioning value as a second satellite positioning value, and the master machine sends the information of the satellite used by primary positioning to the slave machine; S2, the slave machine obtains the satellite positioning value of the current position of the slave machine through the satellite used by primary positioning and adopts the satellite positioning value as a first satellite positioning value; S3, the slave machine sends a difference value which is obtained by subtracting the first accurate value from the first satellite positioning value to the master machine; and S4, the master machine adopts a second accurate value as an accurate value of the current position of the master machine and outputs the accurate value, wherein the second accurate value is obtained by subtracting the difference value from the second satellite positioning value. With the positioning method, mobile terminal and terminal system of the invention adopted, the positioning accuracy of the satellite used by the mobile terminal can be improved.

Description

technical field [0001] The invention relates to a positioning method, a mobile terminal and a terminal system. Background technique [0002] At present, most mobile terminals, especially mobile phones, can use satellites for positioning, and this function provides users with a lot of convenience. However, the accuracy of satellite positioning is generally about 10m, and it is easily affected by the environment. For example, when there are obstacles or tall buildings around when using a mobile phone for positioning, the effect of using satellites to obtain the position will be very poor. At the same time, the satellite orbit Factors such as errors, atmospheric conditions, and GPS (Global Positioning System) antenna performance will also affect the accuracy of positioning, and the first satellite positioning requires a long search time, usually 1 to 2 minutes, which brings inconvenience to users.
