Abstract

The invention discloses a positioning method and a positioning system. The method comprises the steps of sending positioning request signals; receiving positioning request response returned by each base station according to the positioning request signal, wherein the positioning request response comprises GPS geographical location information of the corresponding base station; and positioning mobile terminals according to a sending time for sending the positioning request signals, receiving times for receiving the positioning request responses / receiving times when the base stations receive the positioning request signals, and received GPS geographical location information of each base station corresponding to each positioning request response. According to the positioning method and the positioning system, a large amount of mobile terminals can be positioned only through combining GPS positioning based on satellite positioning of the base stations with limited quantity, the number of communication times between each positioned mobile terminal and a satellite is greatly reduced, the usage of the satellite can be furthest reduced, and dependence on the communication signal state of the satellite is reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of mobile positioning, in particular to a positioning method and a positioning system. Background technique [0002] The current mainstream global positioning system achieves the purpose of precise positioning by continuously calculating the three-dimensional position relationship between multiple available satellites and the ground GPS (Global Positioning System, Global Positioning System) receiver. In the process, the ground control part It is necessary to continuously monitor the operating satellites, and the space part must ensure that there are more than 4 satellites available in the sky above each location at each moment. However, there are currently many occasions where the global positioning system is used in various fields, and the number of terminals that need to be positioned is increasing. For example, terminals such as current mobile smart phones are generally equipped with GPS positioning modules. With ...
