The prior art GPS system (Global Positioning System) utilizes a GPS positioning satellite to perform positioning and navigation in a specific range in real time. The general positioning target is for various mobile users such as ground vehicles, sea vessels, aircraft, missiles, satellites, and spacecraft. High-precision three-dimensional positioning and accurate timing, but with the development of social economy, the user demand is also constantly improving. The use of GPS systems to implement mobile objects such as people, goods, vehicles and other locations at different locations is extremely costly. In addition, because it belongs to Space satellite navigation and positioning is difficult to promote in the civilian sector where "small" and "fine" are required.

For example, due to the requirements of safety management and operational efficiency, it is necessary to know the location of passengers in the terminal, trains, museums, traffic, etc.;

For example, due to management and logistics efficiency requirements, it is necessary to accurately grasp the location, flow and other information of different goods in warehouses, shopping malls or other logistics links;
