Abstract

The invention discloses a method and a device for comprehensively positioning an intelligent terminal. The method includes the following steps: after a positioning function of the intelligent terminal is started, monitoring the moving direction of a user by a turning detection unit; if changes of the moving direction of the user are monitored, positioning the position of the user by the turning detection unit when the moving direction is changed. By the method, long-term opening of a GPS (global positioning system) receiving unit is not needed during positioning, using time of the GPS receiving unit is reduced, energy consumption of the intelligent terminal is lowered, and more flexibility in positioning mode is realized.

Description

technical field [0001] The invention relates to the technical field of satellite positioning, in particular to an intelligent terminal comprehensive positioning method and a positioning device. Background technique [0002] GPS (Global Positing System, Global Positioning System) is a satellite positioning system first launched by the US government, and has been widely used in navigation and positioning tracking services of various vehicles. GPS has a large effective coverage area, high positioning accuracy, and the error range is generally within 10 meters, and it is free to use. Therefore, at present, various communication devices, such as smart terminals, are generally equipped with a GPS receiving unit to facilitate user navigation and positioning requirements. There are three different start times when the GPS receiving unit works: cold start, warm start, and hot start. When the user does not need real-time positioning, the GPS receiving unit can perform positioning th...
