Abstract

The invention discloses a mobile terminal and a positioning method for freely switching different positioning systems. The mobile terminal and the positioning method relate to the technical field of communication, and are used for solving the problems that the operation is complicated and hardware used for positioning needs to be additionally arranged or changed when positioning terminal equipmentand switching among different satellite positioning modes. The positioning method comprises the steps of receiving a high-level effective positioning signal in at least one path of positioning enablesignals and outputting the effective positioning signal to a low dropout linear voltage regulator by means of a circuit communication device, providing a positioning chip selecting switch with a voltage by means of the low dropout linear voltage regulator, controlling the positioning chip selecting switch to connect a first positioning chip or a second positioning chip by using the at least one path of positioning enable signals, and positioning the terminal by utilizing the connected first positioning chip or second positioning chip according to a satellite signal transmitted by means of a positioning signal pathway.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a mobile terminal and a positioning method for freely switching between different positioning systems. Background technique [0002] At present, most of the consumer mobile phone products use the GPS (Global Position System) positioning function that comes with the platform package to meet the needs of users, but some users in special industries, such as government departments, traffic control police departments, etc. , it is required to support independent Beidou positioning, that is, positioning can be realized without using GPS satellites but only using Beidou satellites; in order to obtain higher positioning accuracy, support for pseudo-range differential positioning is also required. For this kind of demand, the built-in GPS of the platform chip cannot meet it, and we generally use domestically produced independent Beidou chips that support differential functions to ach...
