Indoor navigation using WiFi signals

Every day we use location-dependant services, but there is still a lack of information in terms of a popular indoor location system. In this paper we show methods and some advantages of using already installed infraestructure such as WiFi Access Points to get navigation information. For these purpose an indoor navigation system was implemented using both inertial sensors and WiFi signal strength information. The whole system architectute, both hardware and software, is designed with a modular aproach in order to make easy the test and benchmark of different algotithms and data fusion techniques. Basic algorithms have been implemented to validate the whole system using simulated data through a software-in-the-loop setup.
