Abstract: This paper presents a global localization system for an indoor autonomous vehicle equipped with odometry sensors and a Near Field Communication (NFC) reader to interrogate tags located on the ceiling of the environment. The Near Field Communication (NFC) reader can measure the phase of the signals coming from responding tags. This phase has non-univocal dependence on the distance robot tag, but in the considered frequency, it is really sensitive to a change in the position of the robot. In this system is used for surveillance in security applications. For this reason, a multi hypothesis Kalman filtering approach provides a really satisfactory performance even in the case that a very small amount experimental tests, an average position estimation error of about 4 cm is achieved using only two tags for an area of about 5m2.
