A method () to determine a present position () of an object (). The method () comprises using () an optical positioning system () to determine a first preliminary position () and using () a radio-based positioning system () to determine a second preliminary position (), determining () a supposed position () on the basis of one of the preliminary positions () and combining () the supposed position () with a previous position () of the object to determine the present position () of the object, if the supposed position () is based on a different positioning system () than a previous supposed position ('). A positioning system () with combined optical and a radio-based determination of a position of a tracker () and a tracker () with an active light source ().

Embodiments provide a data receiver with a unit for receiving sub-data packets configured to receive at least two sub-data packets from a data transmitter, and to combine the at least two sub-data packets to obtain a data packet that is transmitted split into the at least two sub-data packets by the data transmitter, wherein each of the at least two sub-data packets is shorter than the data packet, a unit for receiving sub-data packets configured to receive the at least two sub-data packets on at least two different carrier frequencies a unit for determining a phase difference configured to determine a phase difference between the at least two sub-data packets that is caused by the at least two different carrier frequencies and the path delay, and a unit for determining a distance difference configured to determine a distance difference between the data receiver and the data transmitter based on the determined phase difference between the at least two sub-data packets.
