Using the Magnetic Field for Indoor Localisation on a Mobile Phone

Part of the Lecture Notes in Geoinformation and Cartography book series (LNGC)


Many people have difficulties getting their bearings when entering an unknown building. However, this problem can be solved by localisation and navigation on a mobile phone. This chapter presents a locating system which is based on recognising geomagnetic field disturbances and ambient light. A particle filter is applied to the locating problem. It is used to fuse together the data of both sensors and track the mobile phone. The prototypic implementation of locating takes place on an Android tablet. Different aspects of the particle filter are evaluated regarding their influence on the accuracy of locating. The tests took place in an office building. In the course of these tests an arithmetic mean locating error of 4 m was achieved.
