Abstract: System for detecting a person on an underground, which is provided with passive RFID tags (1) in a predetermined pattern, while the person is provided with a sensor module (2), which is adapted to determine the position thereof relative with respect of to the RFID tags and, preferably, the direction and/or the acceleration and/or the inclination thereof. The sensor module and/or further processing means are arranged to calculate the position of the sensor module by means of triangulation calculation. The tag pattern is formed by a regular pattern of tag clusters (4), each being formed by two tag strips, oriented in a T-shape with respect to each other. Of the T-shaped clusters, the first tag strip has an even identification code and the other tag strip has an odd Identification code. The RFID tags are applied to construction foil, which is positioned under the top layer of a floor.
