Multi-information Fusion Technology for Positioning System

In the positioning system, the effect of the cumulative error was happened which will result in inaccurate positioning if single technique was applied in the system. In this paper, multi-information fusion technology was used to realize the precise location in the positioning system. Firstly, the Wireless Local Area Networks technology was used to achieve a wide range of positioning. Then Radio Frequency Identification Devices technology was used to achieve small range positioning. Finally, the two technologies were combined to realize the precise location of the system. Experimental results show that the application of this technology is feasible.
