The relation between realization effort for a positioning system on the one hand and positioning accuracy on the other hand is improved by using, for determining the position of a mobile portable device, two sensors within the device, namely one sensor for detecting the movement of the mobile portable device as well as one sensor for detecting the approximation of the mobile portable device to one or several reference beacons, wherein, from a knowledge of a position of the one or several reference beacons by means of data provided by the sensor detecting the movement, the position of the mobile portable device relative to the one or several reference beacons is calculated. |
