Abstract

The invention discloses a portable electronic device which possesses function of energy-saving and energy-saving method; it fits for portable electronic device which possesses global satellite positioning system (GPS)module and process module, and the GPS module is used to receive satellite signal and position based on the satellite signal, and the process module is used to control the integral running of the portable electronic device to make the GPS module receive satellite signal and calculate geography position information of the portable electronic device based on the satellite signal, and the GPS module stores and sends geography position information calculated for the process module to output the geography position information, and when the GPS module judges geography position information stored maintains the same, geography position information is stopped to send to the process module, and the process module enters sleep energy-saving module. So, the invention controls running of the portable electronic device based on result of positioning to save power.

Description

technical field [0001] The present invention relates to a power-saving technology of a navigation device, in particular to a method for saving power for a portable electronic device with a global satellite positioning (GPS) function. Background technique [0002] Global Positioning System (GPS) is a recently emerging communication technology, which has a wide range of applications, such as positioning and navigation for moving objects such as ships, automobiles and airplanes; for network time synchronization such as electricity, post and telecommunications, etc. Provide time service and frequency calibration service; also provide high-precision measurement guarantee for geological exploration of different levels. With the continuous expansion of application fields and the continuous advancement of science and technology, in recent years, various manufacturers have devoted themselves to developing handheld GPS devices, which can be used to determine the latitude and longitude...
