Abstract

The embodiment of the invention provides a locating device and a use method thereof, the locating device comprises an original data acquisition unit, wherein the original data acquisition unit comprises a gyroscope, an accelerometer and a barometer, the gyroscope is used for acquiring the movement angular speed information of the device; the accelerometer is used for acquiring the movement acceleration information of the device; the barometer is used for acquiring the atmospheric pressure information of the device; and the device further comprises a wireless communication unit, the wireless communication unit is used for transferring the information which is acquired by the original data acquisition unit to a processing terminal, and the processing terminal calculates the location information of the device. The use method of the locating device is that other location coordinates are corrected through determined location coordinates. The device and the method can determine the relative or absolute movement path of an object in an area without a global positioning system (GPS) signal.

Description

technical field [0001] Various embodiments of the present invention relate to a positioning device and its positioning method, especially a positioning device and its positioning method used in areas without GPS signals. Background technique [0002] With the development of science, technology and economy, more and more fields and users need to use location services. At present, the Global Positioning System (GPS) has been able to provide users with very accurate positioning services. However, to use the global positioning system, it is necessary to accept wireless GPS signals transmitted by satellites or antennas. For areas where the signal cannot be received or the signal quality is poor, such as tunnels, underground facilities, indoors, interference shielding environments, etc., GPS signals cannot be used to locate. [0003] In many fields, it is necessary to obtain positioning information in a special environment where GPS signa...
