Title:
DIFFERENTIAL GLOBAL POSITIONING SYSTEM AND A POSITIONING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/177951
Kind Code:
A1
Abstract:
A differential global positioning system (100) and a positioning method therefor. The differential global positioning system (100) comprises a base station (110) and at least one smart device (200). The base station (110) is configured to set first positioning data (x1, y1) of a fixed location when the fixed location is set. The base station (110) comprises a first signal receiver. The first signal receiver receives a satellite positioning signal sent by a satellite system, so as to obtain second positioning data (x2, y2) of the base station. The base station obtains differential correction data e according to a measurement error between the first positioning data and the second positioning data. The base station (110) can perform communication connection with at least two smart devices (200), so as to transmit the corresponding differential correction data e to the at least two smart devices (200).
