Tiivistelmä
Recently, with the development of GPS which can provide satisfactory positioning out-door solution, research has turned to the area where the GPS signals could not reach: indoor space of the infrastructure, especially for those huge buildings like shopping malls, airports and museums. Indoor positioning system has become one of the hottest topics in computer science and engineering. Plenty of research resources and funding have poured into this attractive area to find a best solution with satisfaction of accuracy of positioning and acceptable cost.
However, there is not yet one perfect solution in this area for the sake of both less initial hardware investment and accuracy with good satisfaction. To find a solution which requires no initial hardware investment and gains satisfied accuracy, researches on the theory of indoor positioning system was carried out in this thesis. By comparing the existing technologies to realize indoor positioning system, conclusion can be made that geomagnetic localization might be the best hope to provide the perfect solution for indoor positioning.
Based on the theory of geomagnetic localization, with the API provided by IndoorAtlas, an application running on Android platform was developed in this thesis. System architecture and other design details for the software system are also presented. The experiment was conducted on the third floor of Building A in the main campus of TAMK. Evaluation of performance and the result of the application software for the system are also given. The test result for the system shows that the accuracy of the system should be acceptable.
