Nowadays, mobile phones have a multitude of sensors: WIFI connection, Bluetooth, GPS / GLONASS, inertial sensor (IMU), etc. Due to these sensors, one of the applications that can be given to these devices is the location of users on a map. Outdoor location is a field that has already been solved with GPS / GLONASS , but with respect to indoor location need more time for a complete development.
The current project is born from the need of the Lopsi group (Localization and Exploration for Intelligent Systems) of the Center for Automation and Robotics belonging to the Superior Council of Scientific Research (CSIC), to develop a indoor positioning system.
The system will be composed of a server and multiple mobile devices. This system will allow the location of multiple mobile phones with Android operating system. These mobiles will connect to the server deployed on a laptop via WiFi connection. Thanks to this connection, they will transmit the information of the different wireless networks and the data of the inertial sensors of the phone itself. With this data, the server will estimate the position of the telephone, and transmit it to all connected devices, showing the user position in the map, and offering him a guide for the environment.
