1. A system for determining a position of a moving object, comprising:

  • an arrangement comprising at least three general lighting LEDs, wherein a first general lighting LED of the at least three general lighting LEDs is implemented to transmit a first light signal comprising a first transmission time information and a first transmitter information in a first wavelength range, wherein the first transmitter information enables at least a determination of a position of the first general lighting LED and the first transmission time information is information on a point in time when the first signal was transmitted, wherein a second general lighting LED of the at least three general lighting LEDs is implemented to transmit a second light signal comprising a second transmission time information and a second transmitter information in a second wavelength range, wherein the second transmitter information enables at least a determination of a position of the second general lighting LED, and the second transmission time information is information on a point in time when the second signal was transmitted, wherein a third general lighting LED of the at least three general lighting LEDs is implemented to transmit a third light signal comprising a third transmission time information and a third transmitter information in a third wavelength range, wherein the third transmitter information enables at least a determination of a position of the third general lighting LED and the third transmission time information is information on a point in time when the third signal was transmitted, and wherein the first wavelength range, the second wavelength range and the third wavelength range at least partially overlap in an overlapping range;

    a light sensor mounted to the moving object and implemented to receive the first to third light signals in the overlapping range and allocate a first signal receive time to the first light signal, allocate a second signal receive time to the second light signal and a third signal receive time to the third light signal, andan evaluation unit which is implemented to determine the position of the object based on the first to third transmitter information, the first to third transmission time information and the first to third receive time information.
